While I was wrenching on the car today i had an why not put rear disc on the car and oversize Wildwood or Brembo kit on the front since it will probably be needing brakes by the end of the year if not sooner.

anyone with experience with this or any hints as to where to look?
I checked both sites and neither company shows for a 1999 Bonne

Tint it so dark, you won't even know your name

I know you won't find a 4 piston caliper kit for your car. I don't know what you're going to find for rear disc conversions.

Maybe you could convert to an 05 GXP 13" set up. You would need all the parts including caliper brackets and bolts. 18 inch wheels also.

Would they mount to a 92-99?

I noticed an early-mid-90's Regal GS with rear discs today. I wonder if those might be more compatible.

Would an F-Body swap work on the fronts? Thats what Im thinking about doing, but I have an 00+ so might be a lil diff than the 99-

_________________

I upgraded to F-Body front brakes using 00+ knuckle, W-Body strut/spring, 92-99 top-hat, and some minor modifications.

viewtopic.php?f=12&t=3044&p=29756
It needs an update. (and has some typos) I used a shim to make up for the difference in diameter of the strut shaft and top hat ID.



You can easily with an 00+ it's just a matter of shimming the bolt holes in the knuckle to accept the smaller F-Body bolts or drilling and taping the F-body caliper brackets to accept the larger 00+ bolt. This wouldn't be much of an upgrade since 00+ already have a 12" rotor.

The upgrade is for the dual piston calipers mostly, not for getting bigger brakes.

they may possibly be an option coming from the w bodies, but they are rather small (9in maybe, not certain), and solid rotors as well. prolly wouldnt justify a swap over the existing drums imo.

Another thing I forgot to mention is there had been a rear disk brake swap on an H-body:
http://lesabret.com/phpBB/viewtopic.php?f=7&t=2331

I wanted to (and still might) do a rear disk conversion but the main thing holding me back is pedal travel. There is already a little bit of extra pedal travel with the F-body front brakes due to the extra volume of the dual pistons.. And I know that even a single piston rear caliper will require a good amount more fluid to do it's job. So, I'm not sure where that will put my pedal.. I was thinking that a smaller piston caliper wouldn't do too much to the pedal travel but who knows.. I would think that a master cylinder from a GP would cure pedal travel issues due to the rear but they have a differnet ABS setup..

As far as straight up mounting goes, the easiest thing to do is to find a rear disk brake that is mounted via a mounting plate and the mounting plate has the same bolt pattern as the 92-99 hub. Problem is, most rear disk setups are bolted to the knuckle like they are in the front. The link above shows that a pontiac 6000's mounting plate/caliper/disk will work on a 92-99 rear knuckle. I know F-body cars have a similar setup but the bolt pattern doesn't look like it matches up..

And finally you'll have to get adjustable proportioning valves to replace the stock ones since drums require less pressure to operate.

Last year I was seriously considering converting to 4-wheel disc, but since I'm done modding (in hopes of acquiring a new car, but currently just letting the funds slowly build up as well as the credit score) I've put those plans to the curb.
What I was hoping to find out with a trip to a salvage yard was to see if a set of rear hub assembly's from a mid-late 90's Cadillac Seville would work on 92-99 Bonnevilles.
I'm thinking those would probably be the closest, but for now 95nsta's may be the easist way since there is a good write-up.

And upgrade to stainless brake hoses should firm up the pedal feel as well.

95naSTA, maybe you need a diff proportioning valve for the for your front swap or did u already do that? did u follow the procedure for properly bleeding your brakes with ABS? Cuase I know some cars you need to criss-cross from side to side and front to back.

_________________

There's no external valve for the fronts. And the pedal travel issue is a result of the two pistons having more volume than the original single piston. This is a known issue with this upgrade. Some use C5 Vette calipers when they do the swap because their pistons are slightly smaller but otherwise are the same.
When I bled the brakes, I did the longest line first to the shortest.

18"s aren't needed this setup clears my 17" stock ssei wheels.
