OK so i just got my check form uncle SAM looks like i been a good boy this year. so i want to a whole brake up grade now i have a v6 3.1 firebird about to be turbo in the spring and i want the stopping power to live up to the horsepower .


now i was going to replace the Master Cylinder
convert the drum to disc in the rear or just get a other rear form a car that's has them.
then convert the single piston front to dual like on the v8 version of my car

NOW heres the questions

1. Will the dual bolt up or do i need to change the Spindles.
2. Is there a certain way i need to hook up the brake lines in the rear after getting the discs.
3. Is there a difference between a v6 and v8 master cylinder
4. and rotor size is the same or are the v8 a little bigger ?

 

Modification of the spindles is required: http://web.archive.org/web/200605221.../1LEbrake.html
If you swap in a complete rear end, no. If you convert, you'll have to bend the hard lines to fit the calipers.
No.
Same, front and rear, if you're discussing the rotors and calipers found on 82-88 cars. BTW, unless you have a 1LE, the front rotors/calipers (10.5" rotors and single-piston Delco-Moraine calipers) should be the same as the 82-88 cars.

BTW, if you swap rears, consider drive and/or driven gears, along with parking brake cables, and a disc combination valve. More info in the following link:

ok well could i get spindles for the 1LE they will fit right ? because all these cars are really the same.

if i swap the whole rear would i have to get a other parking brake cable
and i can use the same Master Cylinder but i just going to get the 1LE one off rockauto.

and the rotors are 10in ones front and back ? for the 1LE package

 

The 1LE spindles are quite rare; as a consequence, finding a pair would be difficult and expensive. You'll have to modify. The 1LE package is equipped with 11.+" rotors and dual-piston alum calipers on the front. The rear has 11.+" rotors and a single-piston calipers. Check my Car Details below for pics, if you desire. Also, read through the above link. The rest of your questions will be answered there, I think.

ok thinks .... i just really on the fence about this because the whole brake job see being done my my friend and his dad because they have a shop and lift to make it easier.
but im already 900 in the hole with a complete brake job..

 

I know this isn't the answer you're looking for, but it's a common sense approach. You could double the stock horsepower of your 3.1L and the stock drum/disc breaks should still have no problem stopping the car under most conditions. If your braking feels terrible now with 140hp, then your stock brakes are in rough condition. All the stock disc/drum brake parts are dirt cheap, since they're basically the same as every mid-80's-early 90's S10, Malibu, Monte Carlo, etc. You can replace damn near every piece of your disc/drum brakes for under $250. That's including the master cylinder, calipers, wheel cylinders, rotors, drums, front and rear pads, all new hardware for the rear, new rubber hoses, etc. If your car is as worn as most thirdgens, the $250 brake overhaul will make a world of difference. Sure the 1LE or another conversion will stop better, but it'll probably cost you at least another $1,000 over the disc/drum setup.

 

nope that's what I'm looking for thinks ... see my problem is i see something that new and i think it better which is not the case most of the time. I'm think dual- pistons over my single how can i lose lolol. but your right when i first got my car the guy had drilled and slotted rotors and ceramic pad and that thing stopped on a dime ... so think man I like people like you because u see it form a practical sense ... got my reality check for the day thank 250 is much better then over a 1000 lol

 

If you just want to rebuild your brakes to stock, check out... www.rockauto.com They've got really good prices, and usually have a bunch of parts on closeout for fractions of what they'd cost locally. For heavy parts like rotors and drums, check local prices at the discount stores (Advance Auto, Checker, Autozone). Do some bargain hunting and you can probably bring the job in under the $250 mark. Also don't forget coupons... Rock Auto always has a 5% off coupon, just google for a current code. Advance Auto puts out coupons every month, they've always got discounts for online shopping on the website, and if you sign up they'll mail out coupons too. 20% on purchases over $100 come in handy. I'd bet the other discount chains offer similar discounts.

 

well i order everything off rockauto in the long run i get what i want and no trip back forward to the store -.-had to return a calpier like 3 time it wasn't finished then wasn't cut right what a headache

 

You can, but you'll probably pay a bit more that way. Shipping might get expensive on the heavy stuff.
