Ford F-150 - 1997-2003 :: Rear Drum Brakes Locking Up
Sep 10, 2009
I'm having a problem with my rear drum brakes locking up when I press the brake pedal. I've had this problem before, but ignored it because it wasn't too bad. It would just release after taking my foot off the brake pedal.
1998 F-150 XLT supercab 4x4 front discs, rear drums 4.6L v8 175k miles
I cleaned my master cylinder and bled all brake lines so they have fresh fluid. Now that my brakes work way better, my rears just lock up. I put new brake cylinders on, still locking up. I went to a junkyard today and replaced the proportional check valve, brakes still locking up.
Could I maybe have did something wrong when cleaning the master cylinder? I'm sure I put it back together correctly. Anything else i should look at? bad lines maybe?

Changing rear drum brakes to discs? I've done it with my 94 explorer, and i was wondering if the axles are the same, just swap the hardware like the explorers are.

I got a 2002 f150, right now it has a 9.75 with disc brakes. But it exploded. I can only find a 9.75 with drums in the wrecking yard. Can I just swap my disc brakes on to the axle with drums?

I have a 1997 F150, 4X4. My mechanic says its time for new brakes and was curious if it would be worth possibly converting from drum brakes to disc brakes??
My mechanic has quoted me $300 to do the rear brakes, would it be worth the extra money to convert??? I really don't care for drum brakes. I have done a search on the internet and every time it brings up the issue with the parking brake.

Recently purchased my first Ford truck, a 97 F250 w/7.3L diesel. I discovered the passenger rear drum brake was full of oil. Cleaned it up and put it back together to do some research.
I see how the hub comes off and there are two bearings in it an an oil seal. The bearings are lubed in wheel bearing grease. Does differential oil circulate through the bearings too?
It doesn't look like a difficult job. Do the seals go bad often or could this be due to a clogged differential vent? Truck has only 100k miles. Any gotchas I should be aware of?

I've got a 1997 Ford Expedition 5.4 with 200,000. So my rear differential leaks a few drops of fluid every time I drive it, looks like it's coming from the pinion seal. I've just been filling it topping it off with fluid.
Anyway, yesterday I got in it and started driving, I noticed a howling noise, and when I turned my rear tires started locking up. It was like that for about 5 miles until I got home, no matter which way you turned the tires would lock up.
I went under and topped off the differential with fluid again, and I pushed my parking brake in and released it. Got back in the truck and drove, and it was fine. What happened? I'm just worried it will happen again if I don't look more into it.

Received the truck, 1989 Ranger XLT long bed single cab from my mom. It had been used by my younger brothers for some years, and then sat at mom's for a couple years.
It needed new front brakes badly, so replaced rotors, and pads. No unexpected problems there.
Looked at replacing the rear. Both adjuster cables were initially broken, so they obviously weren't adjusting, or braking. Replaced with a hardware kit, and shoes, and drums. Its the 9" drums, BTW.
Still not actually braking. I can tell this, when at a stop sign in the winter, with the brake pedal held down, and the backs will still spin, with the tranny in D. Even on gravel or grass, this'll happen.
One shop told me this is because the axle seals are leaking. THey've never leaked badly, and the axle fluid isn't low, by and shade of the imagination. Also, this theory falls apart, when the parking brake works just fine, right? Its just hydraulically that they don't work.
I've since replaced the wheel cylinders, the brake line from the frame to the rear axle, and the master cylinder. No change. Bleeding them doesn't seem to be a problem; i.e. no lack of or little fluid witnessed, it seem fine.
Also have bypassed the RABS valve for about a year or so, and its made no difference. Last fall I pulled the drums off, and manually adjusted them, and it didn't seem much better either.

I didn't put the rear drum on while adjusting the rear brakes, now the drum wont go back on because the brakes are too far out. How do I get my drum back on! This is on a 2002 Camry LE

I have a 2000 CR-V with rear drum brakes that make quite a bit of noise. When I press the brake pedal, they make a noise like the shoes are grinding on something other than the drum itself. Also, when I press the pedal at the right amount of pressure at the right speed, I get a loud high pitched squeal as if there's a metal tab rubbing on the drum. I did this brake job with my dad about 6,000 miles ago (154xxx miles now) including the front pads. We did everything right and bled the brakes VERY thoroughly.
We used the same drums as before (however, we replaced the front disc rotors) and everything is how it should be. I even adjusted the shoes' pressure on the drum a bit to see if it would stop. Also, the squeal noise seems to be worse when I haven't driven the car for about 2 hours or in the morning when it's colder and the brakes haven't been used in several hours. What's causing these noises?

Just need to know how common this brake adjusting lever is? Awhile back I rebuilt my whole brake system and for some unknown reason the DS rear drum brake wants to keep over adjusting. Checked and double checked everything but can't see what would be causing it.
The fix has been to pull the wheel and drum and back off the adjuster but that's getting old. If I had more time and enthusiasm, I'd switch the shoes and hardware side to side to see if the problem follows the hardware. My solution for now is go with manual adjustment and to disable the DS adjuster by cutting off the end of the lever.
Before I hack up a lever I'd like to have a back up in case there is any problem. Not sure if the junkyard will have what I'm looking for and don't see the correct style lever on Rockauto or at my local parts places. My luck is to cut up a part that's hard to find.

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.

So when I got this truck everything on the brakes were messed up. So long story short I got a new master cylinder new pads and all lines are bled. Now this hole time my ABS light has been on so I looked at all the sensors and i found one connector that goes to the rear axle but it has no where to plug into. But I also found some writing on the axle which tells me that is a different axle and may not have had ABS set up. But I am not sure. Now the problem I am having is when I hit the breaks i don't have much bite but if i push on them harder the rear will lock up and the front brakes are biting just a little like 50% power. So how can I get more stopping power to the front pads ? And if its that unconnected sensor is there anyway i can loop in out of the system ?.

I have a 1998 f150 4x4 4.6 triton V8 regular cab, I would like to ditch the rear drum brakes in favor of disk brakes. is this an easy bolt on project? I do know that 2003 f150's had rear disk brakes and was wondering if i bought those parts if the procedure would be fairly easy. I know i would have to take a check valve out of the master cylinder to gain pressure to the rear.

I just had new shoes, hardware, wheel cylinders, drums, leaf springs, rear shocks, and shackles put on. The brakes were done about 4 or 5 months ago and the springs and shocks just a few weeks ago. The rear brakes were locking up after I had the work done, but I thought they were just too tight. I loosened them a little but it only worked a little.
Now it's starting to lock up pretty much every time I apply the brakes. The ABS kicks on and the rear tires skid. I took the drums off today and didn't see any leakage or anything out of the ordinary. They weren't too tight and I readjusted them but they weren't out of adjustment much if at all. I looked at the Ford symptom chart and it says for brakes that lock up easily there could be sticking or binding components. I didn't see any. Then it says check parking brake components.
Now I see they didn't hook up the equalizer bracket that goes to the front leaf spring hanger when they changed my springs so I assume thats why my parking brake pedal goes to the floor. Then it says check the shoes and linings, which are fine. The last thing it says is to check the fluid control valve. Which I'm guessing is the prop valve.
The only way to check it according to Ford is swap it for a known working valve. One person told me that it could actually be a bad brake booster check valve. Is that possible? Anything else that's common? It's got 272,000 miles on the frame but everything's been changed that typically wears out at least once.

I have a 2004 Ranger 4x4, 4.0, auto and have trouble with the back brakes howling, locking up and generally driving me nuts. I've replaced the drums, shoes, cylinders, emergency brake cables and all the hardware. We've bled all 4 numerous times, blown out the lines, looked for leaks and done all we can think of. What am I missing?

I've had this "rattle" when going over uneven roads for about the past few months and I think I narrowed it down to the rear calipers. They are both tight, but it seems as though the "floating" ability of the caliper is loose.....does that make any sense? I mean you can grab the caliper and it'll make a rattling noise, but the bolts are tight..

Went and got new tires on the supercrew. Went going through parking lots or simply driving i hear a loud squeal like brake pad squeal. I put brand new wagner ceramics on the truck. Also if i turn to the left the driver side rear sounds like brakes are dragging against the rotor. Whats goin on with this. The squeal will happen between 10 mph to 20 mph and the grinding noise will happen if I am cruising or turning to the left. It goes away when i apply the brakes.

2001 F150--V8-4.6-3.55--8.8. 221000 Miles. Changed front rotors and pads. Had scrubbing noise from right rear when applying breaks heavily. Changed rear rotors and pads. Still have scrubbing noise when breaking hard. I do not hear any noise when driving regular or when normal breaking. Differential fluid was a tad low. Applied fluid. Still have scrubbing noise. No leaks at hub seal or pinion. Bearings ? Maybe?

I have a '99 Ford Ranger XLT 2WD. I've been having this problem with my rear brakes locking up on me while slowing down and pressing the pedal to stop the forward movement. There are four components which could cause the problem. My OEM Ranger Repair Manual suggested to replace the Proportional Control Valve which I did however that did not correct the problem. I don't have the Brake nor the ABS Warning light coming on and they check out OK during the start up. I have no problems braking from any speed except when coming to a stop. I inspected my front disk and the rear shoe brakes and they seemed to look OK. The other components which could cause the problem are the Control Module, RABS valve and the Speed Sensor. My question is: If any of these components malfunction, shouldn't the ABS Warning Light come on?

I replaced the master cylinder 2 months ago and now every now and then the rear lock up for a second. its only happened a couple of times. Pulled the wheels and everything is in place with nominal wear with clean drums and rotors. Am at a loss as to why this is happening.
