Ford Ranger Brake Problems

buster15buster15 Posts: 38
The truck stops fine (most of the time)on occassion and its becoming more frequent just prior to a complete stop the pedal goes down with a mushy almost vibrating feeling and I keep rolling ahead 2-3 feet.
I had a new M/cylinder and ABS Module installed yesterday and a major brake job 2 mos ago. The brake booster is good and there are no vacuum leaks or fluid leaks.

A scan shows everything ok.

Help please...
Thks for your advice.



  • The Chilton manual says:
    "Warning: Vehicles with 4-wheel anti-lock brakes require an anti-lock brake adapter(t90p-50-ALA) and jumper (T93T -50-ALA)in order to bleed the master cylinder and HCU. Failure to do so will trap air in the HCU unit, eventually causing a spongy pedal."
  • Dave, did you ever figure out your problem as you described?? Just happened to me exactly the same way, please respond

  • I have the same problem. The Ford dealer performed a PID monitor test of wheel speed sensors with all reading correctly. Ford Tech hotline stated that one sensor probably reading "dirty voltage" checked voltage readings each wheel speed sensor while braking. One wheel sensor was inconsistent with the others so they changed out speed sensor.($480)
    But... the condition is still there so I returned to Ford dealer. Now they say that they suspect wheel speed sensor, wheel hub tone ring is internal in front hub. They are unable to see ring itself so they what to replace hub. What do you think?

    I have the towing package brakes with the 11 inch rotars.
    Cheap garbage, a brake job costs me 150 dollars every thirty thousand miles, and I do it myself. The rotars warp, the pads wear unevenly, and the bearings are shot each time. Someone told me it has to do with the ABS, and that it can warp your rotars and do a lot of damage. What do you think?

    i have a'90 ranger 2.9L v-6, my brake light and RABS light have always been on but i didn't notice a problem. now my front brakes are locked on, any idea how to fix this?

    Sorry for the late reply,

    After a new M/cylinder, ABS unit and a lot of down time, Ford diagnosed it as a faulty front left wheel sensor. Cost was $690 cdn. I noticed driving in snow is at times scary. When I picked up my truck a lady was in service with a 2003 Escape, same problem.
    This is my last Ford... ever... I am going European. Too bad for Ford and they can't figure out why their profits are down and their plant closures are more frequent.

    I got sucked for the front left wheel hub assy too. They build the sensor into the hub so it is non-replaceable. A tacky way to screw you for your $$$$. It seems to have fixed the problem by 97%. I suspect the other 3% is the right side starting to go.

    ok i can compress my calipers and drive my truck but as soon as i hit the brakes they stay, autozone told me that the rubber lines is the problem so i replaced them same problem. ? are my calipers bad? i can compress them with no problem, is it air in the line or could there be a hole in my lines somewhere else please i need help its all i have right now thanks

    I just got my '01 XLT 4x4 fixed. Same problem. They replaced the front left sensor, but not the whole hub. See my posting in the maintenance and repair thread. Reply #2469. I had shared info with Buster15 there in the past.
  • bad caliper same thing happened to me. i replaced caliper and they worked fine. The piston in the caliper is all messed up cant do much but replace it

    Hi Buster15 I also had the same thing happen on my 2000 Ford Ranger and I am going to take it into the shop. I was wondering if you have change out the other sensor or if your truck has improved . It sounds like the brake systems being more complex the mechanics just pick a maybe part and hope it will fix the problem Thanks for your posting I think it will save a lot of people some $$$. :lemon:

    Hey Gene,
    After alot of incompetence on behalf of some questionable mechanics, the right side has not been changed. I notice if I am slowing down @ 3-5 mph and crank the wheel hard right I get the same symptoms but not as bad. I am afraid to deal with the local dealer here as a lack of trust exists (they always lift 500-800 bucks from your pocket).

    The truck was not good on the snow this past winter so (hopefully) come fall I am going for a Santa Fe.
    By the way I got all my money back for the new ABS unit and Mastercylinder.

    Picked up a 'free' 92 as long as I could get it running as it was sitting for about a year. Couple parts later: drive line(busted off on freeway on ride home), battery(owner left dome light on, and fuel fill pipe(someone cut to siphon gas). SO, on to my issue. Brakes - When I drove the truck home, no problems with my brakes. I drove the truck for a few days, then I noticed a strong smell and smoke after a short drive from front brakes. Checked reservoir, low. Added more dot3 and pumped brakes POP brake line near gas tank broke due to corrosion(rust). Fixed the line, bled brakes and replaced pads. Still smoking if I drive it. weird thing is; they dont grab right when I start driving, it takes a little bit of braking before they slow me down. Is this a master cylinder issue? power booster? any other ideas?

    Thanx a ton

    Bad caliper, or bad rubber hose which can collapse internally and not let fluid flow backward which keeps the brake engaged.
  • hack360hack360 Posts: 2
    so i guess you mean bad caliperS since both of them are sticking? and what rubber hose are you talking about? the ones on the truck are separated. they come from steel lines and go to rubber at the wheel well. i dunno just seems funky to me.

    Can a pro verify if the front wheel sensor (is this the ABS sensor?) can be changed by itself without changing the whole wheel hub assy.

    If possible, is it a difficult job or can I do it in my driveway? The left sensor and hub was replaced now the right sensor may need it. Can someone direct me to a link showing the sensor in the hub?

    Thks :D

    Off to the Ford dealer this a.m., this p.m got a call, now the right ABS hub sensor is gone. Interesting fact the hub and sensor is now $300.00 Cdn down from $390.00 (genuine Ford parts). Must be down due to the high sales and turnover of wheel hub assy's.

  • I recieved my ranger in 2005 with it being an 02 model only having 18,000 on it. Excellent condition. Well, when i would hit the brakes, the steering wheel would shake. So, about a year and a half ago i bought new roders. Now it's shaking all over again. I don't know if maybe it's the calipers or something. I still have warrenty on it (extended service plan). ---also the brake pedal makes a spongy squeak like noise, but it's been doing that since i had it.
    AND i have to apply more pressure to the brake pedal to stop than i do in another ranger.

    I really would like some comments or suggestions. Right now it's at the dealership getting under warrenty aircondition service. But, I want to make sure they don't rip me off.
