      Members Only Fluid Forum View   08/08/2017

      Fluid forum view allows members only to get right to the meat of this community; the topics. You can toggle between your preferred forum view just below to the left on the main forum entrance. You will see three icons. Try them out and see what you prefer.   Fluid view allows you, if you are a signed up member, to see the newest topic posts in either all forums (select none or all) or in just your favorite forums (select the ones you want to see when you come to Fishing Minnesota). It keeps and in real time with respect to Topic posts and lets YOU SELECT YOUR FAVORITE FORUMS. It can make things fun and easy. This is especially true for less experienced visitors raised on social media. If you, as a members want more specific topics, you can even select a single forum to view. Let us take a look at fluid view in action. We will then break it down and explain how it works in more detail.   The video shows the topic list and the forum filter box. As you can see, it is easy to change the topic list by changing the selected forums. This view replaces the traditional list of categories and forums.   Of course, members only can change the view to better suit your way of browsing.   You will notice a “grid” option. We have moved the grid forum theme setting into the main forum settings. This makes it an option for members only to choose. This screenshot also shows the removal of the forum breadcrumb in fluid view mode. Fluid view remembers your last forum selection so you don’t lose your place when you go back to the listing. The benefit of this feature is easy to see. It removes a potential barrier of entry for members only. It puts the spotlight on topics themselves, and not the hierarchical forum structure. You as a member will enjoy viewing many forums at once and switching between them without leaving the page. We hope that fluid view, the new functionality is an asset that you enjoy .

Soft Brake pedal

Recommended Posts

Wade Joseph

Ok, I have a 98 F150 and I have replaced every component in my brakes both front and rear with the exception of the actual lines, and the antilock unit. I have bled them numerous times and the pedal is still soft. Anyone got any ideas?

Some newer vehicles with ABS have very specific bleeding procedures different from what we may have done in the past.

The traditional longest to shortest method may not be the right bleeding sequence, and also some ABS valves have to be purged by activating the ABS system. Shops ususally do that with the electronic service tools.

Dunno if all that applies to your truck, but it did to my Buick.

Is the pedal soft or low?

Are the rear brakes adjusted up good?

Does this have 4 wheel abs, or just rear abs?

Did the hydralic system ever go dry? ( brake fluid)

If the pads and shoes are new, did you give them time to brake in?

If everything looks ok, then you may need to bring it into a shop and have them do a service bleed on the abs pump.

Can you give us a time line. Basically from the beginning what happened and what you tried in order to resolve the issue.

Rarely do we have to "bleed the ABS" after replacing hydraulic components.

My bet is that you replaced the master cylinder with a remanufactured unit. If this is the case you have two choices. Keep replacing with remans until your pedal returns or try a new master cylinder. It is not uncommon to have to try several reman units to get one that actually works. I have also had the same thing happen with new units but typically the second one will work fine.

Yeah, I did get a bad reman master cylinder one time.

Pedal was not soft, it just went completely to the floor on an intermittent/random basis. Talk about a scary feeling!!!

Well, lets see. First I replaced the front brake pads. I used a C clamp to compress the calipers and get the new pads in place. I then bled the front brakes. Pedal was soft. But not that bad yet. Truck still seemed to take longer to stop. I pulled the back drums and the shoes were pretty thin, so I replaced the rear shoes complete with a new spring kit. Brakes were worse. I could not bleed rear brakes as the bleeder screws were frozen. Then between 25-30 mph I got a bad vibration and strong smell of hot brakes. I then replaced the master cylinder. Same result, still soft and takes a long time to stop. I pulled the back brakes apart again and found the emergency brake cables stuck. Got them pushed back and released. I replaced the rear brake cylinders and the rear drums. Still have soft pedal. I have bled nearly 2 qts of fluid from the system. Never once have I gotton a large air bubble. Today I bought a power bleeder kit. If I don't get good results after flushing and refilling and power bleeding, I think I am gonna have to take it in to a garage.

What brand of brake pads and did you turn the front rotors?

I'm sorry but I have to ask (I've seen some things in over the years that boggle the mind grin.gif ). When you are bleeding the brakes you have somebody pushing down on the pedal while you crack the bleeder screws, correct.

The brand of brake pad is especially important. I have on more than one occasion run into cheep pads that will not stop a vehicle. Replacing the pads with higher quality/major brand has solved this problem in nearly every situation.

On the other end if you replaced them with the "ceramic" pads and your vehicle was not O.E.equipped with them than can also cause braking issues. Not all ceramic pads are created equal and some pads with very little ceramic material are marketed as ceramic. getting back to the point, If they are true ceramics they require more braking force to get the same affect as there non ceramic counterpart.

As far as turning the rotors. If the rotors are concave or dished in the center it can give a sinky pedal feel. It doesn't happen that often but occasional you'll run into it. Making sure the rotors are not only true to avoid pulsation but flat in order to fully transfer braking force is important.

When you pumped up the pedal after installing the new pads did you push the pedal all the way to the floor. Debris will accumulate in the bore of the master cylinder in the places that rarely get used. If you push the pedal to the floor it will allow the seals on the piston to travel through the debris and potentially damage them. Short pumps are always the best option.

I assume that everything was fine before you replaced the pads so I think that the last scenario is the most plausable

if that is true. As far as still having a soft pedal you didn't mention if you used a reman master or a new master. If it was e reman than I would probably either try another or spring the extra cash for a new one. I guess I would also be curious if you bench bled the master before you put it in.

On my full size bronko my brake peddle is soft but it is due to a leak in the vacuum booster.

brakes still work, just takes a little longer to stop now.

No, did not turn rotors, they were in good shape, reman master cyl. have good vacume from booster. Used OEM style aftermarket pads from reputable auto parts store. Maybe it is the master cyl. I purchased a power bleeder and am gonna try to flush system and the master cyl. Yes, I bench bled the master cyl, but am gonna re-bleed it without brakelines attatched with some short pieces of brakeline I purchased recircing the brake fluid back into itself once I empty the fluid thats in it now.

Oh, I forgot to mention, I have also bypassed the rear abs unit by running the line to the back brakes straight from the master cyl.

Bench bleeding requires lines to be returned to the reservoir while you are bleeding? I'm not really sure how you did it the first time.

When you bench bleed it pay particular attention to the fluid being returned. I have noticed a similarity between always having little bubbles come out of one or the other fittings and a bad master cylinder. This doesn't always happen but you can bench bleed the snot out of them with no change.

Keep us posted on what you find Wade!

Well, finally some good news. I had everything disconnected today, I allowed all the fluid to gravity drain. I bled the rear abs unit, rigged some old tubing from the outlets of the master cylinder back into the resevoir and pumped the pedal thill I had good flow recircing. Hooked the brake lines back up, refilled with fresh synthetic fluid, allowed it to gravity bleed till I had good flow at every wheel. Tightened everything up, bled each wheel in sequence, and wallla! I have a good pedal again. I am off for a test drive. It stops well in the driveway.

synthetic fluid


I know ford doesnt recommend synthetic fluid in any of their vehicles, I dont know what aftermarket shops think of it, but I wouldnt use it!

I have been using amsoil or mobile 1 in every ford I have ever owned. This particular truck has 171, 000 miles on mobil 1. Might as well go with the brake fluid as well.

"Synthetic Fluid" ?????

DOT5 brake fluid is synthetic and very few vehicles use it!

DOT3 and DOT4 are interchangable and compatabile with each other. DOT5 cannot be used with either 3 or 4. You MUST completely flush before installing, and there are still frequently problems - the mix of 5 with 3 or 4 causes rubber failures in all brake components - master cyclinder, ABS unit, calipers and wheel cylinders. Don't change to it unless you know what you are doing.

AMSOIL doesn't have a brake fluid available at all, and I don't know of a Mobil1 brake fluid.

      Hello, I'm from Chicago but I have a lot of family in Rochester. I come up for a week every few months and always do great fishing for Large mouth. I was hoping to find some spots to specifically target Pike that are within 30 mins of Rochester. I will be mainly shore fishing.  Thank you 
    • eyeguy 54
      Got up to Bowstring again at Geigers Trails End Resort. Went up to get some crappies nd found them but again could not get one to bite out deep.  One spot they were 7 feet thick ! LOL   So we chased perch and did great. No 12 inchers but a lot of dandies. Not sure if I will get back up before ice.  Crappies should be great this winter.

      Where's the best place to get bait at Vermillion?? Is Hoodoo the best access to fish big bay? The girlfriend and I are going to come up for a day trip tomorrow...Thanks for any help.
    • Cliff Wagenbach
      I believe that there is a campsite or picnic area in the bay just South of the S-Curve  located adjacent to the WMA, I believe that Green Herons and Blue Herons nest in the trees there! Cliff

      Hope everyone had a great summer season of fishing and otherwise, and here's to hoping the fall season is going well.  I'm planning to get some grouse hunting in while up in a couple weeks and noticed Pine Island has a WMA on it.  Figured if I had time, I can take a quick ride out to there and have fun walking around on an island WMA.  Does anyone have any input on difficulty of beaching a boat somewhere along the shoreline on the north or south side, if even possible?   Thanks for the help and advice this year from everyone I talked to on here.  Looking like I may miss out on hard water this year and will have to put cracking that nut off until next year.

      I have a number of family and friends fishing the river Thursday thru Sunday this week.  No reports yet.  I will pass them along as soon as i hear.

      Northwestern and central Minnesota have elevated fire danger due to sparse rain, high winds and lack of humidity. This means that open burning may be restricted in certain counties. The Department of Natural Resources urges Minnesotans to use caution while burning yard waste or leaf piles outdoors and to check the burning permit website for information.  “During fall, we know that residents and property owners will be taking care of leaf and brush piles,” said Casey McCoy, DNR wildfire prevention supervisor. “Piles can smolder undetected for several weeks under the right conditions. Windy, fall days can reignite these piles.” On average, Minnesota issues approximately 43,250 burn permits annually. When weather conditions warrant it, state fire team leaders may turn burning permits on or off. To determine whether burning is allowed, Minnesotans should regularly check their county burning restrictions. Residents may need to find alternatives to burning such as composting or hauling brush to a collection site or wait until it is safer to burn. “If you do decide to burn yard waste or leaf piles, do so when there is less wind,” said Linda Gormanson, burning permit coordinator. “Instead of burning your yard waste and potentially causing a wildfire, compost or chip your yard waste or bring it to a collection site.” Burning restrictions do not apply to campfires; they are still allowed. Clear an area around the campfire, watch it continuously and make sure it is out cold to the touch before leaving. Fire danger can change quickly. Check the Minnesota Incident Command System site https://goo.gl/W686km for fire behavior conditions. For questions about burning restrictions, check the DNR page at mndnr.gov/burnrestrictions or call your local Forestry office. Discuss below - to view set the hook here.

      Lots of boats on the river daily here in LF now.  Select people are hitting good pods of fish and catching well.  Flows, though still Very swift, are slowing.  Fish are becoming a little more scattered, more fish are being caught away from shore and away from prominate structure. Minnows and tubes pulling most fish.  A few nice fish here and there most are falling in the 15-17 inch range. Good luck out there.
