Will softer or bigger brakes increase foot brake stall?

Tim Ellis · 06-30-2011, 10:07 AM

I can only hold 3000 before the rear tires start to creep, flash is around 42-4400.Need better r.ts so I'm hoping to increase foot brake stall.

You will need to increase your pedal ratio so you get more psi withe same amount of foot pressure. I just bought a used pedal and change the spot were the master cyl is attached. You still have the stock brakes on it I beleive not sure whether you ilminated the power brakes or not yet, which master cyl do you run? You asked me about my brakes this last weekend on my car. Talk to me in Woodburn in a couple of weeks.

3000's not bad for that tight a coverter.

This is a little off topic,,, but congratulations Tim, on going deep in the combo on both days last weekend. It was a decent turnout for Bremerton, which usually doesn't have a lot of S/SS cars show up throughout the season.
West Coast,, it was good to see you at our track also,, although I didn't get a chance to talk with you. Good luck the rest of the season to a couple good Mustang racers.

Re-shoe with a fork-lift brake shoe material. It is softer

I got my shoes relined today with some super whammy supposed trick stuff, we'll see if it helps. I do know my shoes and drums were quite glazed. I don't have a line lock, so I have the brakes on during my burnout, and I'm sure that ain't helpin anything except the glzing issue.

Tim, I agree with both James and Jeff, but there other things you can do. What kind of car are you running? I'm assuming this is a street/strip car since you have power brakes. You could install an adjustable brake prop. valve but thats not the best idea. Yes, that would give you more rear brake pressure but then you run the risk of rear brake lock up if the race is real tight. Another is a master cylinder that has more capacity for the rear brakes and bigger wheel cylinders along with the softer shoes. If you do alot of street driving with the car, bigger brakes wouldn't be a bad idea, but you will have to add bigger wheels and tires to fit the bigger brakes. An extra ten feet of stopping distance could mean you can still race that night instead of having it towed home and a ticket for a rear end collision. Study what you have and look up parts that are bigger and bolt on from the parts store. I found out front brake calipers from a mid 90's camaro with v8 will bolt up to my 86 Olds Delta fwd, and they have a bigger piston. Rick.

1989 O/sa and N/sa Stocker Mustang, all stock brakes except new shoes I'll be tryin. Has plenty big rear tire, 30/9/15 Hoosier radials. If the shoes don't work I'll see how James idea works, if not, it's back to the drawing board, or take a bump.
