Car pulls left slightly-rear brakes the cause?

My car has a slight pull to the left so after checking that the lines had not collapsed I thought that maybe one of the front calipers was seizing slightly. Not so, well at least when the brakes are cold. However, tonight I felt the rear drums after being out for a drive. The pass side was warm to the touch but the drivers was scorching hot. I'm not guessing that the driver side rear drum is not ajusted correctly and it is this that is causing my pull to the left?

I had always associated pull with the front brakes and never thought about the rears causing the problem.

Opinions please.

Robert

I've been having similar strange experience with braking. It pulls to left also, but feels like sometimes its actually the rear moving to the right causing front to move to left.

How do the rubber boots look on your pistons?

Pull your pistons out to see if any of the chrome is rusted over.

If its the rear, maybe a suspension prob (i.e maybe need boxed in LCA's or tubular).

I just redid my brakes about a month ago (front disk rear drum). I'm going to completely drain, and fill the entire system w/ synth brake fluid. The fluid naturally absorbs moisture and *** knows when the last time it was drained/filled. At this point, I guess it could be several things, but I think fluid and bleeding is a good place to start.

Rubber boots on the piston looks good. I checked it and gave it a squirt of WD40 to make sure it was moving freely.

did you really have to force that driver side drum over the shoes? Maybe pull it back off and adjust that little star wheel back until you get a little less contact. I hate drum brakes.

Matthew,

Yes, the drivers side was really tough to get back on. I'll pull it off tomorrow and adjust it. This was my first time of ever messing with the drum brakes. I'll be getting discs in the future as drums are just a pain.

Thanks everyone. I'll update when I adjust something.
