calling everyone with rear discs, and those who know about them.

[1Badelky]

anyone used these? Hassle free drum rear disc conversion to 1LE/ LT1 PBR rear brakes - Brake Board - Third Generation F-Body Message Boards

Supposed to utilize PBR brakes for third gen f-bodies. Do they require shock relocation on g-bodies?

I'd use LS1's but they require cutting the mounting surface, drilling and tapping, and relocating the rear shocks to clear the caliper. I don't want to cut and fab.

Then there's SSBC. are they good? how about mods required? Performance Disc Brake Search Results from Stainless Steel Brakes Corporation (SSBC)

Then scarebird. Any experience? Scarebird Classic Brakes LLC

are there any I missed?

which is the best with extensive mods? what can I expect?

[1Badelky]

oh, and do the aftermarket companies use GM wear parts? (pads, rotors)

[1Badelky]

TTT

I'm leaning toward the PBR or LS1 brakes if I can somehow aviod clearance issues...

Hassle free drum rear disc conversion to 1LE/ LT1 PBR rear brakes - Brake Board - Third Generation F-Body Message Boards Now that's the way to do it! Most people hack the hell out of the flanges. That adapter looks like what most of the companies that make 4WDB kits use. I want to use those with the 4th gen discs on my car. I dont see why the shock would have to be relocated. It looks tight but I'm thinking the PBR caliper clears. I'll try and dig up a pic of the G-body plate I've seen.

[1Badelky]

hey thanks. I believe the caliper clears, but the ebrake linkage interferes.

Any luck with that G body plate?? I looked at his demo and his axle in the pics looks g-body'ish?? Im curious if those plates will work??? Looks like a clean and reliable way to go!

[1Badelky]

the ones for the 10 bolt f-body rear are the same as ours. the thing is, the f-body guys don't have the shock right there next to the flange to worry about, hence my problem.

[Hot Air]

I bought my Baer rear disk brakes from Cottons Performance and love them. The fit great and work outstanding. The emergency brake even works!
Conrad

[1Badelky]

can you get the pads and rotors at an auto store? or are they special from Baer?

[Hot Air]

I would think that the pads and rotors would be available from non-Baer sources but have not looked into it. Anyone know for sure?
Conrad

[1Badelky]

I've eliminated the following from my options:

scarebird- iron caliper if you want a parking brake, and are low performance and require the axle to be machined down

wilwood- requires same mods as LS1 for an ungodly price. unless you want the drag lite bolt ons with no ebrake provision... no thanks.

the first SSBC link I posted- iron caliper, non-GM wearparts, requires flange to be drilled and tapped.

I have narrowed it down to the following:
PBR kit from Ebmiller88- most likely what I'll get

if that doesn't work out I still have:
LS1- cut the flange down and relocate the shocks, but no possibility of ever going back to metric flange.

SSBC Stainless Steel Brakes A127 - Stainless Steel Brakes Rear Disc Brake Conversion Kits - summitracing.com- 11 rear brakes, aluminum caliper. bolt-on, but still relocates shocks, just includes the L-bracket which doesn't look sturdy at all. also uses special order pads you only get from them, so very unlikely I'll use them over another kit.

Baer- almost identical to PBR setup but uses C4 parts instead of Camaro.


these are all the kit's I'm aware of with the exception of the speedway motors kit which is truly a POS. iron calipers, small iron rotor, non-GM wearparts... I'd rather have the drums than this kit. there's all the pros and cons in a nutshell in case someone else is wanting to look into this.

What About ...baer Iron Sport Rear Disc Brakes With E- Brake ,795.00 Dollars ...this System Is Suppose To Be Bolt On And I Am Told They Fit Our Cars

[1Badelky]

well, I'm gonna try Ed's kit. I'll post back with whether or not it worked out.

[rangelov]

On the brake mounting flange there is step, near where it goes to the big mounting bolt. The hassle free drum rear disc conversion mounting adapter doesn't have the step. It looks as if he just cranked down the bolt until it stops. The plate looks bent when tightened down. This adapter is made for the rear discs from '89-'97 F-body


Scarebird accomodates this step in his adapter. Scarebirds adapter is made to fit the Eldo calipers.

I wonder why the hassle free conversion mounts the caliper so low.

[1Badelky]

I noticed the step, but thought nothing of it..... I'm reconsidering LS1 now. I don't want scarebird because I have to machine the axles. I'd rather cut and tap the mounting surface, but mount the calipers toward the front side of the car like on Camaros so I avoid shock interference.


I'll ash Ed about the step.

[charlief1]

subscribed

[1Badelky]

well, I think the problem could be corrected by spacing the bottom of the plate out using washers where the bottom bolts go in.





for those of you with LS1 brakes, why don't you just swap the backing plates around so the caliper will be mounted in front of the axle tube instead of where the shock is? does the bumpstop bracket interfere?

[Hot Air]

Don't forget about the emergency brake and the accompanying e-brake cables. You do want a functioning e-brake!
Conrad

[1Badelky]

well, I got a response. he includes washers to correct the problem.

I'll be using Lokar universal ebrake cables.

[mach.80]

How much will this cost in the end. Also, who do I contact if I'm interested as well?

[1Badelky]

the plates are $85 shipped. contact ebmiller88 on thirdgen.org.

I still have to buy the rear rotors and calipers and shoes. I don't know what that costs yet.

if I can't make the factory parking brake cables work I'll have to get the lokar ones.

I ordered the plates, and expect them around wednesday.

[mach.80]

Great thanks for the response. Keep us posted.

Hey Badelky,

Did you ever find a way to get the e-brake cables to work? I have done a conversion to the PBR disks and I want to get an e-brake setup that works.

Thanks

Aerospace components has a setup that is a bolt on for our cars.....

[2toneWE4]

Dude, Get the LS1 rear brake assembly and do the minimal fabrication that it takes to make them work. It is a piece of cake if you have the tools!
That way you can go to ANY parts store for replacement parts(i.e. rotors, calipers, pads, hardware, etc.)
Not too mention, that you will stop better than most F-bodies OR should! When I stomp on mine "I feel my brain slap the back of my eyeballs!"

[Hot Air]

OR, you could just buy the Bear system from Cottons and have great brakes and e-brake!

Yea I looked at the Baer system for the rears and for $1300 they charge about $600 more than I put mine together for. The only difference that I could really see between the set I got and the Baer system was that they had the Bear E-brake cable setup for our cars is bolt-on. My set has the same PBR calipers, and drilled and slotted disks as the Baer Sport Track at a little over $600.

It made sense that for much less than the $600 I saved I can get the proper ebrake setup from some other vendor or at the very least fabricate something up that make my Fbody ebrake cables work.

Here is a pic of the Baer Rear brakes:

Scarebird has redesigned the brackets. See: Scarebird Classic Brakes LLC
These are designed to be use the 82-85 Cadillac Eldorado rotors and calipers. (Cadillac Eldorado 1982-97 rear rotors and 1979-85 calipers).

Ed's brackets are also bolt on.. See: Hassle free; drum to disc rear conversion brackets . These are designed to use the 92-97 Camaro brake caliper and rotor.

The axle flange may need to be machind for both kits. On the camaro brakes, it depends on which rotor is used. It may be a hassle. The axle shfts have to come out anyway. If you plan ahead, it won't be that big a deal or cost that much to machine the axleshaft flange OD.

And while you're at it, install longer wheel studs. The axles may need to be out to have enough clearance to install the studs. You may or may not need them with rotors that are thicker than the drums. Note: Aluminum drums are thicker than iron drums.

Studs: NAPA P# 641-1581 ½" longer than stock,same as Dorman 610-323.

[regal81455]

I chose to use the LS1 conversion and it was a piece of cake to modify the mounting flanges however I do not have a car that is worth more stock, its just a highly modified 81 sport coupe so the savings vs modifying an otherwise perfectly nice 8.5 for me was a no brainer. I got the entire job done for under $250.

[JDSfastGN]

Just for the record, I have LS1 rears and have a working E-brake. Baers are not the only option for having a working Ebrake.

[JR'S1QUICK86]

Just got my brackets and they look good

[rangelov]

JR,

Which brackets did you get?

Post some pix during your installation.

[JR'S1QUICK86]

lt1 rear disc bracket for gbody. i'll try to get some up as soon as i start

[rangelov]

Time to resurrect this thread with new info.

I got a new Speedway catalog. In it, there is a new rear disc brake kit for "7.5" GM. We all know that 7.5 also means the bastard brake flange type axle that the TBs came with.

This brake kit is a variation on the Eldorado/Seville brake caliper kit. This similar to Scarebirds. This a complete kit selling for $349, or $299 w/o parking brake, not too bad.

I have Eldo style parts and LT1 style parts. The problem with LT1 is that the caliper is huge and requires shock relocation. If you want the parking brake to work, you need special cables or cable adapters and brackets. I haven't tried mocking up the Eldo syle, yet.

Anyway here is the link:
