Newbie to this forum, so I'm sure this has been posted before. If so, just point me to te right thread...thx!

So anyway, I've got the weak 7.5" 10 bolt & want to ditch the drums for a disc setup.

Has anyone done this w/ GM parts?
Or am i stuck shelling out serious cash for serious parts(Baer, SSBC, Brembo) that I really don't feel I need since I'm not auto crossing....I just want better braking & better looks for cheap....


Thanks for the help!

It's possible, maybe, I'm not sure, but even if it is, not really practical.

The flange that the backing plates mount to is quite different.

Best thing to do is go buy a whole disk brake rear end. Avoid the older cast-iron cliper ones; look for a 89-up, with the aluminum calipers. They are altogether superior. Unfortunately there aren't a whole lot of them in the world, but they can be found, if you're patient.

 

thanks RB...

do you know if any F body (or other GM) came w/ this 10 bolt & had disc's?

that should help my search & wouldn't make me sound like a total dummy on the phone....lol!!

thanks again!

 

Yes it can be done. It's not that hard to do if you're a little handy with tools and stuff.

AndyZ28 can get you the whole setup complete with cables, backing plates, and all other parts, but you will need to contact him directly. Indeed, an easy way is just to swap rears but the 3rd gen rears are getting scarce. You can find a 4th gen rear that will swap right in but is about 3-4" longer in overall length.

Contact me if you have any more questions, e-mail or PM. I can give you more info than I care to type here.

Try reading this post, Drum to Disk conversion . Also try and purchase AndyZ28's CD-ROM that covers the swap in detailed photos.

Trust me finding a complete '89-'92 PBR rear in good condition can be a tough task.

I'm trying to get my 1LE swap done before moving onto the rear brakes, since the majority of the stopping power comes from the front brakes.

Be sure to contact Ed for little questions, he always there to help.

 

thanks guys

hopefully this will get me pointed in the right direction!

 

When you're in the yards, keep in mind that 82-88 rear discs had a recall out for the caliper pistons. The recall kit is only $40, but it's yet another reason why 89-92 PBR's are better. Either system (82-88 or 89-92) can use your current (RPO code = J50) master cylinder.

Oh and 82-83 use standard (SAE) threads for the brake lines. 84-92 are metric threads and will bolt right into your system. Chances are a junkyard axle's rear caliper brake tubes will be rusted to the tube nuts, and the tubes will snap as you "think" you're loosening the fittings. http://www.classictube.com and others sell stainless steel rear axle brake lines; you'd never have to worry about rust again. They also sell regular steel, but for an extra $20, I'd go with stainless (and I will be when I get that posi fixed and can put my 3.73/posi/disc axle back under my car).
