front brake	Sign In

i have a 94 gmc half ton pickup the drivers side brake was dragging then would almost lock up. so i replaced the caliper and the bolts and sleeves the bolts slide in and still having the same problem . it will do fine for a while and then gradually build up pressure and start dragging .i let it set overnight and its okay for a while the next day . any thoughts or suggestions?

Usually when this occurs its the caliper and or guides/sleeves,which you replaced, and /or the rubber brake hoses to the front caliper(s).
The hoses restrict/collapse internally and wont let the fluid return.
Simple way to check ,when its dragging/binding,crack open the bleeder on the caliper and if the fluid shoots out and it frees up,thats it.
You should have noticed something when bleeding after replacing the caliper.
It is recommended to replace both front hoses if thats the failure.

There was someone on here recently with a foreign car that had a similar concern that turned out to be a faulty brake booster.
I personally have never replaced a booster on a gm vehicle for one wheel locking up.
Usually always is the caliper or brake hose.
My money is on the hose.

See what the others say
Good luck
Jim

Jim's right, the brake hoses over time collapse or start to brake down leaving pieces of the rubber lining in the fluid and stopping up the pin size hole in the caliber.

Re: Brake Flex hose hydraulic lock	Sign In

The brake hoses can fail like a "Reed Valve" shown square above and a flap of rubber allows pressure to pass thru to apply brake as in the arrows shown but then can't return so that brake stays applied. It then gets warm and expands applying more braking force. When all cooled down fluid contracts and may behave which is just another means to cause hair loss in auto repair.

As Jim said. If you just crack open the bleeder a tad the dragging wheel will free right up if this is in fact happening which it almost certainly is,
