#2 of 44 rear brake self adjusters by mike2250 Oct 18, 2006 (11:27 am)
My rear brakes will not astay adjusted. The master cylinder was replaced without any improvement. No one can give me the procedure for adjusting them. The dealer doesn't know but says it's the parking brake does it, but on my Z71 it doesn't last. The standard backing up also only lasts a short time. Any clues will be helpful.

Replying to: mike2250 (Oct 18, 2006 11:27 am) What year is the vehicle? Not sure why the dealer replaced the master cylinder, that has nothing whatsoever to do with rear brake adjustment. Perhaps it's time to try a different dealer.   I think most vehicles now use the parking brake as rear brake adjustment, however, if you don't use the parking brake all the time then they will get out of adjustment from wear. If the parking brake is not effectively adjusting the brakes then it may need servicing/adjustment.

Replying to: mike2250 (Oct 18, 2006 11:27 am) I agree with the previous post, its time to find a new shop. A dealership that can't figure out how to adjust brakes is blowing smoke. I don't understand why they changed out the master cylinder, unless it was leaking. Even if that was the case it doesn't have anything to do with rear brake adjusters backing off. What are the symtoms that make you feel its a problem with the adjuster backing off? Now days with disk brakes in front and drums in the back, most of the braking energy comes from the front. Some autos in the past with rear drum brakes used the parking brake to adjust the rear brakes by a pumping action on the parking brake handle.
#5 of 44 Colorado frozen parking brake by rmseman Feb 15, 2007 (9:38 am)
When the temperature gets to 10 degrees F or lower the parking brake on my '05 Colorado freezes. Even when I haven't applied the brake the night before. First time I took it to the dealer they cleaned and adjusted the shoes. Next cold snap I had the same problem. Dealer removed plug from backing plate "to assist in venting". Those occurences were at 16K and 19K miles. I now have 38K (just beyond warranty of course) and problem is back big time. I'm trying to get it back to dealer when weather is cold enough but my schedule adn the weather's aren't meshing.   Anybody else in the north country having this problem? I'm in western Pennsylvania. It's a manual trans so I need to use the park brake from time to time. I carry a brick in the cab to use as a wheel chock. I never expected to have to resort to measures such as this on a relatively new vehicle.

Replying to: rmseman (Feb 15, 2007 9:38 am) I just bought an 05 Colorado 4x4 Crew with the auto tran and have had the same issue. I live in British Columbia and winter is here so temps are below freezing. I thought it initially because I washed it then it got cold but it happens quite often. Did you resolve your issue?
#7 of 44 Parking Brake Spring 04 Colorado by detalr1 Feb 01, 2008 (11:57 am)
The emergency brake spring on my 04 colorado broke and caused the parking brake cable to snap. When I went to the Chevy dealer to get a new spring, they told me that it was not on the parts list. Talked to engineers at GM coroporate and they did not show a spring on that truck for the parking break. Mitchell's shows the spring on their parts list. I know what was taken off my truck and there has got to be a replacement somewhere. Anyone else having this issue? Any suggestions?

Replying to: rmseman (Feb 15, 2007 9:38 am) Yep same problem. There is a fix for it now, my vehicle just got fixed today. Something about changing adjusters in rear, etc. Said the brakes would absorb moisture.   The problems I now have. In cold it is difficult to downshift (manual) into 1st or 2nd gear until I'm almost completely stopped. Chevy said this is normal. Also difficult to shift into reverse some time to time. Chevy has a bulletin on this (TSB 611), but said it is normal. Anyone else with these problems?   I'm in the process of Chevy buying it back (about 23,000 miles on it). If interested, I'll let you know how it went. Also may just do the lemon law (these problems meet Pennsylvania's criteria). Replies to this message: redseal94 (Feb 14, 2008 1:17 pm)

#10 of 44 Brake Rotor Problem by gmblues May 02, 2008 (11:20 am)
I have a 2005 Colorado with about 50k on it. Started having a brake sticking problem and found the right side rotor rusted, pads glazed with rust etc. As a temporary fix I cleaned it all up so it work right for a while until I can replace the rotor.   Does anyone know if GM had any kind of recall on these things? Rotors should be rusting out on a three year old truck....   Thx Replies to this message: Alennx (Jan 31, 2009 7:59 pm)
