So, I have more information about my braking problems in my truck.
But first, I just want you all to know the emergency brake doesn't work. So, it can't be anything with that.
I took off my tires today to put new pads on them and noticed that my Chilton's manual had the pictures and stuff for an '83 and an '85. You know, the diagrams and how to do it.
Well, my 1985 Ford actually has the 1983 braking system.
Well, when you first start driving the truck in the morning, all the brakes work fine. But after driving it for a while, my RIGHT FRONT TIRE locks up. No other tire does that, except for my RIGHT FRONT TIRE.
After I let it sit for about an hour, give or take a few, I can drive off, and my brakes work like nothing every happened.
Right before my brakes lock up when I go down the road, I hear a major "metal to metal" sound.
This morning when I checked, my pads still had.. pad on it.
I hit your other post. Mine did the same thing, flexible line interior collapse. As others have mentioned, callipers are cheap. Change them both, new flexible lines, new fuid. I changed all on mine F/R. Works great now. Swapped all out in half day taking my time....,
Someone else gave you good advise about "safety issue" parts for brakes are cheaper than hospital bills!
Hi, I was poking around websites today looking for some information on a 351w and noticed your brake posts. Don't know if you got it fixed yet, but I figured I would register, and let you know I had the exact same problem. I was on vacation with my 76 ford van. I tore my hair out trying to find the problem and it turned out to be the master cylinder was bad. Not bad enough so I had no brakes, it was a check valve in the thing that caused the problems. I could drive for a hundred miles if I never used the brakes, but as soon as I started to use the brakes the pressure would build up in the front calipers. First it would just start shimmying and then the brake smell and then the lock up. Wait for an hour and it would cool down and I could drive again. Replaced a bunch of stuff, but not until I did the master cylinder was it fixed. I noticed that it seemed like I could drive further when it was cooler out. The hotter the day the more the engine heat seemed to pressurize the MC.
I would say its in the flexible lines going to your calipers in the front. I had an 82 F-100 that did this to me and like ya'll I just about tore my hair out trying to get it right. Finally got it repaired, and went ahead and replaced the master cylinder just in case.
