I've replaced calipers, brake shoes, speed sensors, brake hoses, brake booster, master cylinder, rear metal brake line, both front bearings. My front brakes will stick and get hot and cause truck to shake at high speeds. Still have problem. No lights no codes.

Good afternoon,

When the brakes stick, do you mean they lock up or just drag?

If you open the bleeder in the calipers, does fluid escape the wheel spins free?

I noticed when I worked on the truck to do the speed sensors the drivers caliper was harder to push in to make it fit with the brake shoes than the passenger side.

You said you replaced the caliper? Why did you have to push it in? Replacements all come with the piston already retracted.

That caliper was already on the truck for awhile and when I serviced the speed sensors I had push the caliper piston In to allow the caliper and shoes to fit over the hub.

If you open the bleeder valve, does the piston push back nice and easy?

I didn't do it that way. I'm going to have to remove it and try it . Would that tell me that if the fluid comes out the bleeder then the hose could be bad.

That is correct or the ABS unit has dirt in it from the module to the caliper.

Did you blow through the line from the wheel affected?

I just pushed the caliper in and opened the bleeder and fluid came out but still took some force.

Headed to town to pick one up. They have the one that has the metal piston instead of the phanalic coated one.
