Rear brake issue

Post by jgmsail » Sat Sep 19, 2015 11:58 am

Ok so I have done a lot of work on my car lately. I have put new koni shocks, new upper and lower A-arms, new bushings on the sway bar, new drilled and slotted rotors on all four wheels, new brake pads and replaced the passenger side rear caliper. Have driven it all of about 200 miles. I noticed the rear brakes were dusting pretty bad and putting off a fair amount of heat, I just figured it was wearing the pads in. Today I thought maybe the compensator valve was may malfunctioning so I have bypassed it. After 40 miles they are still putting off excessive heat, the rim measured 200 degrees F and the rotor measured 250 degrees F(per my infrared thermometer) in contrast the front rims were 118 degrees F and the front rotor was 124 degrees F. I do not use the brakes much as I tend to use the transmission to slow down. Any thoughts would be appreciated thanks

Are your brakes dragging?
The emergency brake could be too tight.
The rear pads are not the same as the front.
To adjust the rear brakes, first loosen the e- brake cable completely and then push on the pedal a few times. The wheels should spin freely and the brakes not drag. Then set the e-brake. Jack the car with the differential and not body.
The old brake lines could be blocking internally and want replacement.
The booster could need adjustment.
