Hoping someone here may have some experience with the issue. My son's 2011 Aveo has an issue with the brakes. I have replaced the front and rear bearings, the front pads, rear shoes. Was working great for quite sometime. Now it has an issue the behaves like the brake is engaging without depressing the brake. I had him in the car with it in neutral and while pushing the car about 4 feet i said, "hey why did you press the brake?" He had not. His feet were on the floor. Tried again, another 4 feet or so and bam, locked up again. You can be driving along and all the sudden feel the drag. Then you have to rev high just to get the car going 10mph.

Also mentioned the pedal will sometime just stop halfway like he is hitting a wall. Release and try again and the pedal behaves more normal.

Thoughts?

Thanks,
Big D

Re: Non-Chevelle repair question.

Had that happen to me one time years ago when a brake shoe lining came loose and would get wedged in between the other shoe and the brake drum.

Big D or Bug D?

I thought the same. Last year there was a siezed drum. Which is what prompted the wheel bearing. Shoes replacement including new springs and self adjuster. Lifted the car, tires spin freely. Drum slid right off. Maybe i get lucky and it is the other side of the car. I will find out soon enough.

Other side drum came right off with little effort and all looked good. If anything it was too loose so i adjusted the shoes out bit. Any other ideas?

Parking brake coming apart? My wife's 06 Aveo went 90K on her first set of brakes. Wheel bearings went at about 60K.

Brakes have been replaced on all four corners as well as bearings, springs, and auto adjuster. The calipers float like they should, everything behind the drums looks good as well. Right now the only thing i can think of is that one of the front flexible brake lines is collapsing?

Open the cap on the master cylinder and look for what looks like some gel or gellatin kind of gunk in there. It's possible that someone added some P/S fluid or something similar in the master cylinder.Brakes will lock up like that and overheat the rotors and drums along with ruining the seals in the calipers and WC's.The oil causes anything that's rubber to swell which causes brakes to lock up.
If you catch it quick and you can flush it fast you can avoid having to replace everything made of rubber in the brake system.
Quick lube places with new employees are famous for doing this as they top off all fluids.
