Buick brake job

Hi Folks, was planning on doing the front brakes on my daughters 1994 Buick Century this weekend but I'm not sure what type of bolt holds the calipers on. Does anyone here know for sure. I know some Ford use a large torx and others I've seen have an Allen head bolt. Can't say that I've ever done a GM product before. Is there any special tool I need to buy??
Joe, I know you'll want me to check the cyberparts site so I'll head there after this.

T-30ish on those front drivers. Autozone can rent them to you, or they are dirt cheap in sets from Sears and have a lifetime warranty .

Yes, check autolibrary .

T-30??? Hmmmmmmm....... Thats a new one. What it most likely is is a 3/8 or 5/16 hex. But if it is a Torx it is more likely to be a T-45 or larger. Auto Library does not offer this information. Go figure. The best thing to do is to pull a wheel off and have a look. If you cant get in there with yer head. Get a compact mirror and have a look.
Hope this helps,
Billy

If it has original caliper bolts it will be either 3/8 allen socket or a T500 torx.A t50 can be used in a pinch.

Well it does mention something in the library about an allen bolt holding the caliper in, but, it doesn't say what size. Go figure. The reason I was asking is that I planned on bringing home some tools from work and I'd like to have the correct one to remove the caliper. I guess the best thing to do is to just bring all of my racks of allens and torx, then I'll have it covered I hope.

Toni..... Like Davo and I said, if its an Allen (hex) it is only 1 of 2 sizes. Either a 3/8 (most likely) or a 5/16. I use one that is a 3/8 socket so I can get leverage with my long 3/8 ratchet.

Believe 3/8" allen.Pick up some disc brake grease, think permatex makes some in a squeeze bottle, about 6 bucks. lube the hardware a bit before re-installing, Check hardware for rust and corrosion, plus O rings. Use good quality pad to insure you dont have a squeaking problem down the line

GM calipers haven't been allen in a while (My old rear drives are).

Many of the newer FWDs are Torx.

You're doing the right thing---borrow both racks/sets just in case, but you're going to find a Torx there I believe .

I think I paid under $25 for a Lisle Torx set at a swapmeet and it is USA made with T60 included .

GM parts book doesn't say for the Cavalier I have....some are, some aren't.

He's doing the right thing--bring both home .

Again, Sears has both sets of tools reasonably cheap---that's the route I'd go if I were starting out and didn't have them.

Yea!!!!!!!!!! Success on the front brake job. Turns out you won the bet on the bolts Billy. It was a 3/8" Allen on the head. If I was a betting man, I would have guessed a metric Allen, but , I would have lost that one I guess. Anywho thanks for the moral support guys.
