I live in southern Ontario and was wondering it there are any after marked stores where i can get parts for my 1990 Bonneville SSE. Right now i'm looking for the complete anti-lock master cylinder and lines. If anyone has an answer please let me know. Thanks, Bob

Bob,

The master cylinder I am unsure of, but would think automotive parts stores would be able to get you that part. On the brake lines you may want to PM Randman1, he was able to find a company that made the right sized lines. And they are Canadian.

Assuming your master cylinder is the same as mine, you may want to look into used. Two years ago, I looked for a "rebuild kit", was pretty much laughed at. The dealer wanted $900 US for a new unit, the chain parts store wanted $1100 for a rebuilt unit. I ended up getting a used unit from a Cadillac for $300.

That antilock design was a 2-year only usage, according to the used parts source that found the one I got.

Well, since you have an SSE, you have ABS. Since you have ABS, you have the electronic brakes. That whole setup is far from cheap. You may be having a problem with the pressurizing setup [may want to tell us why you want to replace the master cylinder], since that is a common problem.

Like already posted, a reman master cylinder assembly could cost over a grand.

Unfortunately, there is no such thing as buying pre-bent brake lines unless you have a Chevelle or some other car that is popular to restore. For us, we get to buy 25' rolls of brake line tubing and bend it ourselves. The Teves system also has non-standard sized lines too. The line for the rear is 6mm from the master cylinder to the proportioner valve rather than 1/4" or 3/16". It also uses bubble flares into the rear proportioner valve and flex line junction. Bubble flares are usually found in import cars rather than domestic (North American) cars.

I had to replace the rear lines and proportioner begining at the back of the front door. I have a very difficult time finding all of the parts but ended up with this:

Proportioner valve - Dealer ~$60
3/16" line - local auto parts store in import section. 2 60" lengths, 1 50" length, 1 double flare union
6mm line - A freebie from Triple * Tubing in Canada. I told the GM about all of the problems I was having finding the lines and was nice enough to send me 2 20" sections for free.
1/4" double flare union - Specialty auto parts store that also sold a bunch of hydraulic fittings

Foghorn, another Canadian member, has seen Triple * Tubing at Canadian Tire but not the specific part I was looking for. They might be able to ouder it for you.

Good luck.
