Brakes not releasing

[John08Silverado]

I have a 2008 Silverado 1500, 5.3L. For about a month now I have noticed that my brakes aren't completely releasing when I start driving. My pads and rotors are in good condition and my brakes aren't completely locking up, but they squeak alot now and I can feel like I have to power through the brakes for the first few seconds after I let off. I am not a mechanic but I can tell something isn't right. Any advice or possible fixes would be appreciated.

Gotta love it. GM is great at taking designs that worked for over 7 decades, and creating new and improved problems that defy all logic. Odd symptom, for sure.

 

Possibly dirty, contaminated brake fluid - guess it wouldn't hurt to flush the system, especially if that's OEM fluid in there. Maybe a hose or 2 that's momentarily collapsing ... sticky master cylinder ....

 

Could be any one, or all of the above.

 

I've got a 30 year old Grand Marquis that's still running the original calipers. Had one hang up on me once - flushed the system front to back, pressed the piston back into the caliper, reinstalled, and pumped the brakes up. Haven't had a problem since - that was 2 years ago. I'm pretty sure the fluid was over 10 years old too. They sure don't build anything like they used to ...

09 avalanche front left and rear right calipers started sticking within days of each other. Flushed the break fluid and 4 new calipers it's smooth sailing. Spent about 250 and did it myself.

Easy way to check go for a drive around the block so nothing gets too hot. Jack it up try to spin the tires. Only takes one to kill your mpg I lost about 4 mpg when mine stuck.

Thank you for the advice y'all, unfortunately I will have to take it to a dealer because I just moved to a new area and don't know any good mechanics around. I tried sorting through some do it yourself videos but I'm just not mechanically inclined. This is my only mode of transportation and can't afford to screw anything up.

Dealer is the last place I'd take an '08. Honestly, I'd rather take my chances at a small, private garage than go to a dealer - the nickname "stealership" is there for a reason. Just MHO - it's your money.

 

Check out the guy's bill in the other thread about the heated/cooled seats, for an example.
