How fast on stock brakes?

[OneQuikSix]

I know there are many variables involved, but I was hoping to get some feedback on how effectively the factory calipers and rotors stop the car during breaking immediately after a quarter-mile pass at the racetrack. I've got vacuum brakes at the moment. My car isn't ready to set any land-speed records or anything...I just want to make sure I can stop the car after a pass without locking up the front tires. I only ask because my combination has the potential to trap some decent mph compared to a stocker. I realize anything will be an improvement over the stock brakes. But, if I race at Reynolds where there is supposedly a 3000 foot slow-down area, will my stock brakes be up to the challenge? 3000 feet sounds like a long way!

Stock system stops me.

The stock brakes will work up to a point, but will heat up quickly at higher than 80-90 mph. Then they will need to cool down. If you decide to go with bigger brakes then you have a better chance of stopping after you get going faster. I've actually had the brake fluid boil from brake heat on one of my cars when I went over 120, but I was road racing. It does give you a pucker factor of 10 when you realize that you have to wait until you can slow down enough to stop. Before you go on a "bonzai" run make sure you've got fresh brake fluid in the system and flush it once a year.

Thanks for the replies guys. If I was constantly on and off the brakes (as in road racing) I would definitely upgrade. However, my brakes should have plenty of time to cool off between passes.

I still have stock brakes.

and your ONLY looking for a 10.50 run ha ha ha ha

(still very impressed !!!!!!!!)

Couple of things make sure you replace the rubber brake hoses yes change out the brake fluid. I use the synthetic fluid a bit higher boiling point but Im using my powermaster. I replaced my rubber hoses with the braided hose kit from Russel and it made a great deal of improvement on the tightness of the pedal.

All great to know. I'm feeling much better about keeping the stock brakes...Thanks!

i will be upgrading to the bigger LS rotors 12.25 "I think" or the vette rotors 13" "i think" i always hatted my stock G-body brakes.

S-10 rear wheel cylinders...aluminum rear drums for heat dissipation...all long rear shoes...Russell braided lines to replace the 3 stockers...rear brakes adjusted guitar string tight...fresh fluid...stops on a dime with vacuum brakes.

Stock brakes dont stand up to back to back 120 plus runs real well. Of course weight plays a part in this as well my car is 3560 with me in it and gas. This happened playing on a back road with some fast LS stuff 3 runs over 120 with maybe 3 minutes between hits.

Make sure you have a clamp on the vacuum line! Lose vacuum to the booster the brake pedal gets rock hard and that long shutdown area gets REAL short!

Stock brakes.. SS lines. S 10 whl cly .. 138+ Car is a driver with a good Powermonster

Thanks for your replies everyone. I've already got my hands on most of the stuff to convert my front brakes to the f-body setup. I just haven't yet bought the hubs and caliper brackets. Eventually, I'll make the switch. I just wasn't sure how realistic my expectations of stopping my car above 120 mph with the stock stuff were.
