INSTALLING REAR BRAKES ON 2003 CHEVY TRAILBLAZER

ALL brakes locked up, or just rear? Rear could mean differential is locked up...Sounds more likely while driving it, as cars now have a front or rear valve so all brakes are not lost at one time..

did you check the metering valve under the master cylinder to see if its in proper position? it need pushed back into place before bleeding the system can proceed its too far forward..

Rear heat temp module needs reprogramming, or do like I did unplug it, cause my daughters rear air didnt work anyways

It could be a bad rear blower motor, or resistor? theres a lot under the truck that could make noise, have a repair shop check it and make repairs.

The park shift lock needs adjustment. The solenoid that locks irt inplace maybe the cause of this

haynes manual has photos to show you how to work on rear brakes.

Parts came loose in the drum on the side it's pulling to.the Nail may have poped off if you diden't replace them casueing the brakes to lock up. You have to take it apart angood luck doing it.

Took my Trailblazer to dealership. They replaced both rear tail light socket boards (these are plastic parts that house all of the rear lamps/bulbs and attach to tail light housing) They advised the sockets in the boards have a tendency to go bad. Everything works just fine. Cost of each part was approximately $29.00. Easy to replace yourself and save the labor.

If it was like mine, It sounds like a semi truck instead of a SUV.
It was my fan clutch staying engaged, replace it and everything was back to normal.

if both rear wheels are off the ground, yes. note that they turn in opposite directions.
