How do adjust emergency brake cable after replacing driver side rear cable. Mine is loose.labjalbee - 2008 GMC Sierra 2500 HD - Brakes - 5/4/2013-
5/4/2013 JimmFirst of all, make sure the rear brakes are properly adjusted. The adjustment is made with a brake adjuster tool through backing plate. Driver side access below axle isn't too hard, but the pass side adjuster is above axle and the access is harder.
Lift rear wheels off ground, spin wheels and tighten adjuster until resistance felt and heard, and back off slightly.
To tighten driver side rear parking brake, turn star-wheel adjuster down.
To tighten passenger side rear parking brake, turn star-wheel adjuster up.
The only thing you can do other than getting new brake shoes would be to see if the cable has some slack in it. The place to do this is under the cab on the drivers side. the cable runs on the out side of the frame rails, there will be one cable coming from the left front wheel area. There is a bracket on the end of it with two more cables attached to it that go back to the wheels. If there is slack in the cables you can try and tighten the nut on the center cable.

Why does only my front left wheel squeak when driving, gets louder while braking?ranchnachos - 2010 GMC Acadia - Brakes - 5/4/2013Mileage is around 70,000. Pretty sure it only happens in warm weather, although with windows up and freezing temps in winter climate I can't hear it. I just started noticing it, while windows are down. No warning lights are on.

5/4/2013 CVOCheck the brake pads thickness. The noise could come from the brake wear indicator, it's touching the disc rotors.
5/6/2013 ranchnachosWhat thickness of pads am I looking for to know they should be replaced? I can't exactly see them but the space between caliper and rotor is roughly 1/8 inch to 1/4 inch.

2/6/2013 JimmUsually, the sudden grabbing is related to a sticking / faulty / seized brake caliper, or faulty / worn wheel bearing. Try the many on-line auto parts sources, such as; www.autopartswarehouse.com, www.partsgeek.com and www.rockauto.com for the replacement parts.

12/16/2012 JimmThe source is most likely leaking brake fluid; from the brake calipers or flexible brake hoses. Try the many on-line auto parts sources; such as - www.autopartswarehouse.com, www.partsgeek.com or www.rockauto.com for the replacement parts.

12/21/2012 cmd01758If you dont have any brakes then yeah, you blew a brake line, but, if the brakes are working fine then you need an axle seal. Ill bet if you check the differential fluid your going to find that its either very low or theres nothing there depending on how long you have had this problem. Im assuming this is only happening on one tire.
