Re: Brake Pads
 
NJK 53 I don't know if you caught what Tom was saying. I converted my Malibu to manual brakes when I pulled booster there was 4 studs going through firewall and master cylinder was mounted in middle to line up with push rod so I put holes there and mounted there car would stop OK but would'nt lock up tires no matter how hard you pushed,so later ended up with factory manual brake setup and seen the problem the master cylinder was located on top set of holes with pushrod moved up higher on the pedal,which of course give more leverage,changed master cylinder to top holes has alot more braking power.
metallic pads do take some heat to work but don't think it would to hold in water.
Have you considered your car just hooks so good that it even hooks in the water box LOL

Re: Brake Pads
 
Tried metallic brake pads on my '64 Dodge and they never worked as good as a set of organic pads. They are actually designed for sports cars and roundy round because they are in constant use and retain heat which makes them work better, it's just not possible to keep enough heat in them on a drag race car.

I would get some soft pads and bleed the brakes then see if the problem still exists.

Tom is correct. This could be your main problem. Jim

Re: Brake Pads
 
Rallye Bob or anyone else, do you know of anyone that manufactures a drag race only disc brake pad that fits the stock caliper? I was looking at the Hawk DR-97 pads but I could not find an application for stock calipers.

It is like there isn't enough pad surface area touching the rotor.
You said that "the car seems to be overpowering the front brakes" but you didn't elaborate on one piece of info. Have you had anyone watch the front tires/wheels to see if they are sliding or rolling when trying to do a burnout?

Cheap, soft pads are the way to go. I've even heard of some racers with "connections" have their automotive brake pads & shoes relined with material normally used for forklift brakes, which are suppose to be even softer.

I use the Hawk DR-97 pads on the front, but I have an after market (Aerospace) disc brake kit....
Contact Hawk and get a recommendation for your application.....
