Hey everyone, thought I'd drop in and give an update. I tried everything - including measuring pressure at each cylinder and it all checked out fine. I've not driven the truck much but it's been annoying that the problem continues. It finally dawned on me that I might have a bent axle flange...

Thanks everyone, you guys are amazing. Here's my update: I replaced the left wheel cylinder and both front flexible brake lines, and bled the system thoroughly. So both sides in the rear now have new shoes and wheel cylinders, and the right side a new drum as well. I believe I found evidence...

I've been thinking about that possibility - that the right rear is actually doing what it's supposed to and the others are the problem. I've adjusted both sides the same, though.... But if for some other reason it is doing most of the work, then getting hot, then grabbing more because it's hot....

Interesting. Hadn't thought about a wrong adjuster. Will check but just from my recollection putting it all together they seemed to be correct.

Thanks, these are helpful ideas! I really appreciate your thorough input.

I've had it apart many times since replacing the seal and it's always been dry. It does act about like that, though. I'll take a closer look for any evidence.

Thanks, that's good to know.

Thanks for the info about the proportioning valve. I'm going to replace the left wheel cylinder too so I'll know they're the same, and double check that the short shoe is on the front on both sides. Thank you!

I'll double check that. I'm sure the right side was correct before it went to the shop, I've not paid as much attention to the left. Thanks!

I did have that a couple years ago, but I've replaced the axle seal and shoes/drum so I don't think that's the current issue. Thanks!

Thanks! I have an '83 K30 and '99 Suburban and this seems to be one of the best forums for discussing and learning. Glad to be here.

Hi there, I have an early 1999 (8th gen, '92-'99) GMC Suburban ½ ton that has had a pull to the right for years. I've had several shops try to fix it, including the dealership, to no avail. What I know is that the right rear brake is working too hard. It seems to engage when the pedal is first...
