1988 BW Drums. Looking for an back plate to convert it over to disc brakes. Can anybody help me. I am new at this but this is what i wanted for my Camaro. 383 Stroker. 700r4. BW 9bolt
Hoping someone that has done this conversion can help me here. I have the brackets bolted on, the rotors fit no problem. First question: do both of the calipers mount behind the axle, or are they staggered? I fear I have the wrong calipers. I purchased rear calipers for 1995 Camaro/Firebird and they look quite a bit different than what I've seen here; there is a big counterweight mounted to the parking brake bracket. I received no instructions with my conversion brackets, so I've had to figure it out on my own. I will post a photo of the calipers I have; any help would be greatly appreciated.
The NVH weights were added mid/late 91. The only difference between the late thirdgen calipers and 4th gen calipers (lt1) were they milled the fins off the 4th gen calipers. They aren't staggered on the 10-bolt, not sure on the 9-bolt.
Okay, so I got the calipers centered and mounted. Next question: I have searched until I'm blue in the face; BANJO BOLTS! I bought left and right soft lines for 89-92 rear disc brakes. I have read contradicting posts on which banjo bolts to use. The calipers are for 95 Camaro/Firebird, should I use 95 Camaro/Firebird banjo bolts or should I use 89-92 banjo bolts? And if I should use the 89-92 bolts, where can I get them? I have searched all the main parts places and nobody lists a "rear" banjo bolt, only front. Are the front and rear banjo bolts for 89-92 disc brakes the same part? HELP!
My crystal ball says you probably want to get the bolts that thread into your calipers. I'd strongly suspect they're the same, but you could always verify by downloading the Parts & Illustrations PDF and looking up the part numbers, then compare those numbers to the OEM part numbers Rock Auto shows for the 93-97 cars. If they don't match, usually Google can find the superseded part numbers, so you can figure out if they interchange.
Still having problems. When I tighten the soft line to the hard line, the fitting bottoms out before it seals. I purchased new hard lines (https://www.inlinetube.com/products/ccb82rc1) and new soft lines (ACDelco 18032338 & 19174047) but it seems one or the other (or both) are incorrect. The soft lines are from RockAuto and are spec'd as left and right rear line for 90-92 rear disc brake cars. I'm using banjo bolts spec'd for 1995 rear calipers and they are borderline too long when using the third gen soft lines, as the third gen soft lines caliper side fitting is borderline too thin. It would be great if someone that did this conversion could provide the specific parts (hard lines, soft lines and banjo bolts). Also, the left hard line provided by inlinetube.com runs in front of the axle instead of behind, like I have seen in my searches.
Couldn't tell you which bolts I bought for the rear. Sometimes the calipers come with them, and I've got a few sets of original bolts, so I'm pretty sure I haven't bothered trying to find bolts for the rears. From past experience, some of the crush washers are the wrong size (in every way) and the aftermarket bolts can be too long since they're pseudo-universal instead of application specific. Not unlike any other application, they grind shorter just fine.
What I've done in the past is ID the threads, and measure the length of the bolts I need, and then hit the Dorman catalog, or Napa website. Crossing over the old part numbers works too. Even then I've had Rock Auto send the wrong part in the right package, or the exact part is obsolete. It helps to be flexible, make something that is "close enough" work, or track down old inventory on a secluded shelf. The best way to know which part you need, is always going to be, doing the book work, and research yourself to be sure it's correct.
Got everything installed and working (well, except the parking brake). Big problem was the hard lines that I purchased from inlinetube.com. Wrong fittings installed on the hose end. Wound up taking my original lines and cutting/re-flare to fit. Of course, inlinetube.com will not admit they either sent the wrong thing or built them incorrect, so I'm stuck with $43.00 worth of useless parts. They will not refund, only replace if found incorrect. As I wasn't interested in waiting another week or two and paying return shipping out of my pocket, I'm SOL. Not the end of the world by any means, but still pisses me off. Parking brake is another matter. I mistakenly purchased the shorter cable (1434mm) instead of the correct one for my car (1460mm) that has the self-adjusting parking brake. Fortunately, Amazon has extended returns period so I will be able to return the wrong cables for refund. Ordered the correct (hopefully) cables (Raybestos BC94957) from RockAuto today.
On the positive side, braking is improved. Overall worth the effort.
This is a super old thread. Im swapping my 9 bolt to a hopped up 10 bolt to get more gear ratio options. Is the gentleman still offering the bracket kits to mount PBR calipers to a 10 bolt? If not is there another source? Thanks
Ehh, sort of... Flynbye has a website, and in theory you might be able to order the parts and get them eventually, but it's really not worth the trouble. Assuming you have a good set of 89-92 calipers, then maybe it's worthwhile, but really the service parts support for 89-92 calipers has evaporated. You can't walk into any of the major auto parts chain stores and buy a replacement 89-92 caliper. The rebuild kits are the same way. If you're buying conversion parts you're better off to adapt a caliper you can still get parts for.

By all accounts the PBR caliper with the fins on it is a much better caliper than the replacement GM caliper that was the other caliper offered on rear disc optioned 3rd gens. But I hear ya....
The 89-97 design works great, they're just quickly becoming obsolete, due to lack of service parts. I'm not suggesting the 82-88 caliper is a better choice, it's even more obsolete, and a terrible design anyway. If anything go with something newer, that still has service parts available.

Hawks still offers the PBR set up as a kit as part of the 1LE brake package. A lot of guys roadrace with the 1LE set up as it still works with 16" wheels which I have. https://www.hawksmotorsports.com/198...e-upgrade-kit/
The plate is not compatible with LS1 style PBR rear brakes? Hm how come? Are the earlier style just more popular or what? What's the easiest option if I'm already stuck with LS1 rear PBR?
