I just stopped and smelled brakes. The right rear caliper on my '01 PSD 4WD is locked up. Not completely, but enough to drag and overheat (not enough that I noticed the drag).

I'm out of town but I can grab a reman caliper tomorrow morning. Can anyone give me a quick rundown on what size sockets and such I'll need to swap it out? I have a decent tool kit with me, but I may not have the bigger sockets and I'll need to buy them.

Thanks

 

I can't answer your question as to exactly what size bolts they are, but they're nothing out of the ordinary for the average metric toolkit, maybe 16 to 21mm or so. And I don't recall any being that oddball metric that isn't always included in most sets (18mm?). But I want to suggest that it may only be your slide pins that need cleaning, saving you a bit work in a parking lot if you're not that far from home.

I don't know what the differences are from my e99 and your truck (if any beyond caliper placement - my rears are identical, one's just mounted the other way around) but I had the pins gum up and cause drag.

I was also about 100 miles from home, cleaned it as best I could at a truck rest stop off I-95, and thought it was good. Didn't get back into it when I got home but it seemed fine. Eventually the pins really got stuck, and I wound up replacing the caliper.

Anyway, I'd recommend checking the slides if you have the chance. When I fried my caliper later due to my own laziness, I was home and was able to get what I think are a pretty decent set of calipers, rotors and ceramic pads from Powerstop through RockAuto.

 

Nothing really big there. 13, 14 mm, maybe a 19mm (3/4") if you take the whole thing off bracket and all. If you have anything of a tool kit you should be OK.

 

Don't forget the 10mm for the bleeder valve.

 

Thanks everyone!

I got her back on the road with no trouble. I didn't need to take the caliper bracket off, so a 10mm open end (for the bleeder), a 14mm for the hose->caliper, and a 12mm for the caliper bolts got the job done.

I had serviced my slider pins not to long ago, and they weren't the problem. The caliper itself was sticking. I went ahead and replaced the brake hose while I was at it (a 7/16 line wrench for the brake line and a 10mm for the hose bracket).

Thanks again and happy holidays to everyone.
