the rubber line going to the caliper was bad. replaced the line and bled system and it works great. I think the line partially plugged since this truck has 250k miles on it. I hope this helps someone because I could find very little help for this problem.
not if you re pack the bearings!
The brake caliper boot seal keeps out dust and dirt. If not replaced it can cause the caliper seal to leak and the brakes to possibly fail. It is simple to replace.
bad bearings in it, the compressor, or bearings needs replaced... i just disconnected mine and took the pulley and belt off it.
If you open the bleeder and it releases pressure, follow the steel line back to see if it is pinched somewhere.
It might be the bearings are shot in your jack shaft.
Check your wheel bearings, or you might need a wheel alignment
what would cause a rubbing noise on drivers side front wheel especially when braking ( I replaced rotor and wheel bearings are good) ?
Cam bearings, Main bearings, Rod bearings.
I think we figured it out. Believe it is the throw out bearings.
The brake caliper on the opposite side is seized Example, if it pulls to the left, then the right side caliper is seized and must be replaced.
Faulty ball bearings lead to bearing failure.
Miata wheel bearings are replaced as an integral hub / bearing assembly. Do a search on www.Miata.net for more detailed information. This is true of the FRONT hub assembly, but the rear assembly in the 1990-2005 cars have a replaceable bearing that is the same for all years. Removing the bearing requires removing the entire assembly from the car so the bearing may be pressed out, or gently hammered out with correct drift sizes. The bearings are USUALLY NOT the cause of rear suspension noises. The CV joints are much more likely to fail than the bearings.
