Ford Brakes/Suspension :: After Pressing Pedal Resistance Became Really Soft And Brakes Very Sensitive
I have a 2004 Ford Expedition and today on the freeway I had to step on the brakes pretty hard to avoid an accident. After pressing, the pedal resistance became really soft and the brakes worked, but were very sensitive (a lot of pedal movement to brake). I had this happen some time ago and I did a complete system flush and no problems since then, but it has to do with how hard I hit the brakes. What could be wrong????? BTW - I never noticed the anti-lock brake pedal pulse at all during this event. I'm not even sure it is working at this point. No dash lights to indicate an error of any sort.

I have a 97 F250 that is having reoccurring brake issues, It has an intermittent hard pedal with little to no brakes when it occurs. It will stop but you are standing on the pedal with both feet. I have replaced the booster, master cylinder, and the vacuum pump in the past trying to isolate the issue and still had the problem. On this year model the abs ids only on the rear correct???? if it is shouldn't it only be affecting the rear brakes? Since this truck has a dual reservoir MC the front should still work?

If this was my car or older truck I would know what the deal was. First hill I came down in my recently bought 2003 F250 the pedal pulsed a bit as I tried to slow down...is this the way ABS brakes behave? Never had them on a truck before...she stopped ok but don't know if they are warped or normal ...I'll pull wheels later (not a daily driver)...

After putting my Ford Ranger in park and pressing down on the E-break to get the news-paper or mail. I've noticed that there is a consistent squeaking coming from the back drum brakes when the brake pedal is applied. But only for a certain period of time; then the squeaking stops.
View 8 RepliesToyota - Camry :: New Brakes Squeak After Remove Foot From Pedal
Two days ago I had the front brake pads on my 2003 Toyota Camry LE replaced because they were squeaking when I stopped. That squeak stopped, but after driving about 15 miles, I heard a squeaking noise AFTER I took my foot OFF the brake pedal. Pressing the pedal makes the squeak go away. I took the car back the next day and they changed the front rotors. While driving home, the squeak returned. I took the car to my regular mechanic this time. He says the guys who installed the brakes didn't clean anything when they put the new ones on, so he disassembled everything, cleaned the rotors, etc. and put everything back together. He also said they put the wrong pads on the car - I need ceramic pads and they used the metallic kind. Well, the brakes are still squealing when I'm not pressing on the brake pedal and stop squealing when I do press it.
Characteristics of the squeak....It only seems to happen when I drive the car more than 5-10 miles. When I drive a short distance, it doesn't happen. The sound is rhythmic, not constant. If I step on the brake and let if off slowly, like at a stop light, I can hear it "squeak, squeak, squeak" as the tire rotates. The faster the wheel spins, the more constant the sound. It only seems to come from the driver's side.
I hate to take the car back to the original shop because I don't think they know what they're doing. I'm scared of getting ripped off at one of the big chains (I'm a female and of course whenever I take a car in for service at one of those places "everything needs to be replaced.")
Will Toyota ceramic pads fix the problem? Can the wrong pads cause the brakes to squeak when you're not stepping on the brake pedal? Someone else suggested it might be the caliper binding and that would require replacing it.
Lexus GX 2004-09 :: If Engine Revved When In Park No Deceleration When Letting Off The Gas
My girlfriend said her 2008 GX has been acting weird recently. When in park, if the engine is revved, the RPM's don't drop after letting off the gas. The RPMs do eventually drop but it takes a few seconds and it doesn't do it smoothly. The vehicle also maintains a pretty constant speed while driving and letting off the gas with very little deceleration. Is this normal for this vehicle or could something be wrong with it?

View 4 RepliesFord Brakes/Suspension :: Brake Pedal Goes To The Floor
I did a complete rebuild of my brake system in April. Drums, shoes, wheel cylinders, springs, hoses, pads, rotors, calipers, master cylinder, proportioner valve and flushed all the lines and refilled with synthetic fluid. I have made five trips from Southern California to Idaho hauling home furnishings, one trip to Oregon and one trip to Northern California since overhauling the brakes with everything working great. Now something strange is happening. The brake pedal goes to the floor with very little resistance. It isn't spongy like there is air in the lines. It just goes to the floor if you push it all the way down.
The truck stops ok but it is really scary with the pedal going down like that. You can feel when the rear brakes come on because there is a little resistance in the pedal when they come on. You can actually lock the rear brakes up and skid the rear tires. If you push the pedal down further the front brakes start coming on and if you push all the way to the floor the truck will nosedive and you will get planted in the windshield.
I wonder if the aftermarket Bronco Graveyard proportioner valve is blowing all the pressure to the rear wheels because it won't do it if you take the vacuum off of the vacuum booster. You have full pedal when the booster is deactivated and all the wheels operate normally with the exception of having to plant both feet on the pedal to stop it.
Ford Brakes/Suspension :: 2002 - Pedal Sinks To Floor?
yesterday i gave the 02 diesel a treat, 3 new calipers 4 new rotors, and semimetalic pads. the reason for only 3 calipers is the driver side was just replaced 2 months ago after it locked the wheel up on me. both rears were seized so i only had front brakes, and the passenger side front was leaking.
anyway, all new parts and the pedal is fantastic, besides the truck stopping again. this afternoon on the way home from the shop i stopped at a red light. breaks are rock solid. then all of a sudden, the pedal slowly sinks to the floor. but the brakes still hold. i get home and test them. again, pedal slowly sinks to the floor, but they hold. i am thinking still some air in the system, and park hte truck, with the intention of bleeding them again tomorrow.
i get out and see fluid all over the driveway. great. something in the front of the axle is leaking. the frame is drenched. whatever it is, is in front of the frame, on the engine side. what is in there, the ABS unit?
Ford Brakes/Suspension :: 1997 F150 - Brake Pedal Keeps Fading
I recently purchased a mutt of truck, a 97' F150 heritage w/5.4 Triton motor, 1/2 ton 2WD short bed.
Having a brake issue, the pedal keeps fading. I noticed it first while sitting in traffic on a down hill grade. I am holding the pedal and notice it starts to creep down slowly, I pump it up and it firms up then starts collapsing again. So general logic says hydraulics are loosing pressure right?....No leaks anywhere, so it must MC tight?
I have replaced the master cylinder, brake booster, and both rear wheel cylinders. Long story short they all needed it, truck has 265K+ on the body with 95K on the motor. The only thing I did not do by standard is bleed the MC on the bench, I installed and long bled starting with the right rear working my from longest distance to shortest (wheel speaking). So when bleeding I did of course get air coming out because of the new parts but I still have the same fade issue.
I am confident there is no air in the lines, I have bleed a quart of brake fluid through just to be sure. I have read a lot about proportioning valves and ABS stuff.
I will try and get some vehicle specific photos and attach have hit a road block with this. I am leaning towards the ABS valve thingy mounted on the drivers fender that has four lines attached (2 in and 2 out). Other than that it comes down to hard lines which have no leaks.

View 7 RepliesFord Brakes/Suspension :: 1979 F250 - Hardly Stop When Pedal All The Way To Floor
My problem, Brakes. I hardly have any at all (pedal all the way to the floor and hardly stop), yet the front pads are dragging, and heating the rotors. Maybe a bent line? I bled the fronts, and as soon as I loosened the bleeder nipple, a good bit of fluid came out, without pressing the pedal of course. It's dark out now or I would inspect for bent lines. Could there maybe a problem with the booster?
View 6 RepliesFord Brakes/Suspension :: 1953 F100 - New Master Cylinder - No Pedal At All?
I have a '53 Ford F100. I have a PB conversion kit on it. The master cylinder & Booster are under the floor. I have used this setup for many years. Recently my master cylinder went bad. I replaced it with the same model. I bench bled it, and installed it. I also added a remote fill kit, since it's difficult to check & fill. Because of the booster, the master cylinder no longer sits under the hatch in the floor.
I got everything installed & connected, then bled all 4 wheels using a bleeder kit with an electric vacuum pump. The fluid runs clear & no bubbles, but I can't get a pedal by pumping. I have no leaks. I tried with the engine off, and running. I have felt soft pedals before, but I have no pedal at all, it just goes to the floor.

Ford Brakes/Suspension :: 1987 F350 - Brake Pedal Moving To Floor?
1987 F-350 460 Auto Trans. Brake Pedal slowly going to the floor. Stopped at a red light yesterday on a slight down hill and I noticed the brake pedal slowly going to the floor. I had to put the truck in Park to avoid bumping into the car in front of me. I checked brake fluid level and still at the full level, check rims for brake fluid leak from brake cylinder, none. Could my master cylinder need rebuilding or is my vacuum diaphragm going. Not sure that's what its called.
View 7 RepliesFord Brakes/Suspension :: 2003 F250 5.4L 2WD - Front End Vibration Starts Around 40 MPH
My 2003 F-250 5.4L 2WD has a front end vibration that starts around 40MPH (sometimes) and gets gradually worse until it goes away at 55 MPH. It oscillates the wheel a good 3/4"-1". It also does it also when decelerating through those speeds. It "feels" like the left side, but I can't be sure. When I jacked it up, I could get some movement laterally on the left wheel, but not the right. Also Noticed that the drive shaft has about 1/4" of play at the carrier bearing. Leaning towards ball joints.
