When in reverse, rear wheel(s) suddenly lock up

Are you sure the wheels are locking? I would be suspicious of the park pawl dropping into place due to a linkage adjustment. Is it a 4L60-E trans? (OBD 1)

I don't know what type of transmission my 1995 Chevrolet 1500 Silverado Z71 pick up has other than it is an automatic. Last year there was a leak in the brake line, which was fixed.

Any solution to this? I’m having the same issue with my 1997 C1500

I'm having the same problem with my 07 Yukon 5.3 4 speed automatic. Going forward no problem. Backing up 2-3 feet wheels lockups could it be the transmission in reverse is locking up

The answer for the 1995 Silverado was the rear self adjusting brakes. Instead of adjusting, it was locking. Dealer fixed it along with some other things. It was about $600 at the small town dealer.

1999 silverado Z71 4X4 4L60 all forward gears run fine. in reverse the more throttle the more it binds , never stops engine just labors more but truck doesnt go any faster.it backs just fine till I have to throttle. once is binds it will not move unless I throttle through, and I can get out of the truck and rock againstwhatever it is binding.

My 1996 Chevy Silverado k1500 locks up every once in a while in reverse you give it a little gas it won’t move but when you give it a lot the tires barely spin and it sounds like stuff is grinding and breaking. Any idea what the problem might be?

My car backs up but when I try going forward the front tire locks up

Had the same issue on my 2003 Chevy Malibu. Problem was the rear drum brake locking on one side. Parking brake is a peddle you push down to activate rear brakes and press again to release the brake. I applied just slight push on parking brake foot pedal and heard and felt the brake release. Will pull the rear brakes in the morning.
