View Full Version : Rear Brakes

04-06-2012, 06:03 PM
I have noticed that the rear brakes on my 06 Impala SS are not working right. While I changed the struts on it I held the brakes and you can still turn the rear wheels. When I drive easy they seem to work but under heavy braking I get real bad nose down tail up action. The brakes are new front and rear. The calibers front and rear are new as well.

You may have knicked or bent a brake line to your rear. Did you see any fluid spilled? Check your resovior? I hope you find your problem!

nope. no spills, no leaks, dry as a bone. reservoir full.

Thats strange. The only thing I could think of is a bent line or air got into your lines somehow.

Just asking but why did you change all four calipers? I would try and bleed the system. Double check make sure all bleeder screws are at the top, maybe they were switched or put upside down? How does pedal feel? Could even be a bad master cylinder. Is it both rear wheels?

Um did you remove the plug out of the feed line to the calipers when you installed

They were all done from the dealership that I got it from.

I would defiantly take your car back to that same dealer then. Whatever they did, its all THEIR fault and nothing you did ;)

Ya generally dealers have a 12 months, 12,000 mile warranty on there work they preform

It wasn't warranty work. Plus the warranty is already done on the car

Doesn't matter. They back any work preformed on any car. Doesn't have to be "under" warranty.

your car could be 60 years past warranty, if u take it in for example a window not staying up and they repair it and it falls back down a week later they are responsible and u take it back and have it repaired for free

if the pedal isnt spongy, then it sounds like the caliper's piston is hung up. It happens and even new calipers can be defective. The first generation W-bodies had defective rear brakes, I was replacing my rear brakes every 10 months and twice I received bad calipers where someone could be stepping on the brake pedal and I could still turn the wheel by hand.

Also, however I'm not 100% sure... you could might be able to have a firm brake pedal however the ABS pump might need to be bled as well.
