If your rear brakes are out of adjustment, the parking brake won't even engage. Think about that.

The 'reverse adjust' is clearly called out in the factory service manuals. And works on both of my Bonnevilles.

SSBC MAKES REAR CONVERSION KITS

Busa max, Willwren is trying to say that the factory service manuals for 92-99 and probably 87-91 (unverified 87-91) state that the drums adjust while stopping in reverse. They also mention that the adjustment occurs not necessarily during normal light stops in reverse, it takes a lmore aggressive stop. In looking at the E-brake setup, it is not apparent how using it would keep the brakes adjusted. Please understand, I'm not saying it hasn't worked....I'm wondering..how can it be working.

If this is true, please post a link. Many here would be very interested in upgrading.

Ill admit they had me goin for a second there, then I noticed its for the 82-86 Bonneville, which I guess there might be a couple members here interested in that.

But for a thousand bucks? You could just get some awesome rotors and pads for that and stop even better.

I am not trying to offend anyone especially Bill W, because I think this guy has a lot of knowledge and I am even questioning if I should even reply to this because I am new to this forum.

I understand that the service manual states about the backing up procedure to adjust the brakes. But, if anyone out there that has a rear drum brake car, and they start to notice that the vehicle is doing a nose dive on hard braking, all they have to do to test this adjustment is... for example, at the next stop light, press the parking brake down and release two or three time, and then they will notice that the nose dive is not happening anymore. I believe the parking brake is connected to the adjustment arm that turns the star adjuster on the bottom of the shoes.

I unfortunately no longer own my 1995 SSEi ( I now have a 2001 SSEi) so, I can not show you exactly how this works, but, I would like to request that anyone out there with a rear drum GM vehicle to try this and let us all know if it worked for them or not.
This may not work on vehicles older the 94, but it did for my on my 95 and newer. Good luck!

i have the rear drum setup and it seems like the front breaks are doin all the work, im gonna try out the parking break thing and see how that works. does anyone know if the grand prix rear setup is drum or disk, and would it work for bonneviles. just wondering. I have only had the car for 2 weeks and dont like the rear drums. IS THERE A SOLUTION TO THIS PROBLEM?

yes make sure that your rear drums are adjusted properly....

the Grand Prix uses 4-wheel disc brakes, and I dont believe they will crossover, I know the front brakes dont crossover. Or at least im 95% sure they dont.

I cant recall in my mind the rear suspension setup of a Bonneville, but I think the W-body is entirely different back there, meaning the brake components probably are as well.

yes it is totally different and wont even come close to swap

Ok so we know the 97+ w-body rear discs woun't swap over.. But what about the pre-97 rear discs.
My 90 regal has 4 wheel disk breaks and the rear is set up very different from the 97+ macpherson strut setup.
It has a monoleaf spring setup (a leaf spring that goes from one side of the car to the other attached to the contol arms)
And it has shocks similar to the 92?-99 bonneville.
I could pop the wheel off and take dimensions as needed?
