Default Brake Problems

1989 Ranger, two-wheel-drive, 4-cylinder, manual transmission, two-wheel drive. Front brakes got weird: both got really hot, but the left was worse than the right. During braking, the truck pulled badly to the right. Daughter was driving it and was nearly home when this started so she drove on home. When I went outside to look at it, there was a bit of what appeared to be smoke coming from the left wheel and the smell of something getting very hot. We replaced both calipers, checked and repacked the bearings in both wheels, examined the rotors for run-out and smooth surfaces. Rotors were in great shape, as were the pads which had been replaced only about a year ago. We bled the system, front wheels only, and it seemed to be good. A test run indicated no pull to the left or right, the wheels remained cool, and braking was straight and solid. Now there is a slight "whooshing" sound when the brake peddle is depressed and sounds like it's coming from the power-assist unit. Today she drove it to work and on the way home, the hot smell began again, and the wheels were pretty hot again, though not as bad as last week when this started. What's going on?

If it was the booster you could tell by the brake pedal being soft. Your booster works or it don't work. It can't be going out.

I say its the pads. Check your brake pads for cracks and uneveness,etc.

Cause your brake pedal hooks up to the booter and the booster hooks up to the master cylinder which sends fluid/pressure to the brakes to work them.

take off the front wheels and take a look

put all 4 in the air on jack stands, run it to a slow pace (20 is PLENTY) and hit the brakes and see what happens. watch the front brakes and see the caliper slide properly and retract properly.

Caliper binding on the pins and not sliding back and forth maybe?

If your booster was failing youd feel the pedal on the floor and pump it until you run the red light anyway. Trust me I know

Did you ever get this issue fixed. I am having the exact same issue on a 1990. It is four wheel drive and fully stock. Any ideas?

JCannon, yeah, but I finally gave in and took the truck to local mechanic shop (two brothers -- d@mn good mechanics). They checked things out, said everything was terrific, and it's all working great. If they found or changed anything, I don't know about it. Sorry, not much help. I have since driven the truck (had forgotten how much fun it is to drive) and brakes work great. I started with changing out the calipers; the pads were already new. Wait a minute -- now that I think about it, the mechanics turned the rotors, although they were in pretty good shape. Maybe that was it. Let me know how it turns out and Good Luck!
