Up grading the disc brakes

Bob C,
You make a good point about a stock setup working properly being able to simply lock the wheels.

A quick side story about too much pressure... We use C3 Corvette calipers on all 4 wheels. They get stainless inserts during the rebuild/exchange and last forever.

I got a phone call that the calipers I sent out were bad, they had leaks on 3 of the 4 calipers. I asked him to send them all back and overnighted 4 replacements even though the shipping was an arm and leg. The next day he called and said the new ones were bad too as the pistons blew right out of the caliper body and so did the stainless sleeves. I am thinking NO WAY but did not have the old ones back yet to see for myself.
Turned out he modified the system to get more brake by changing the bore diameters and pedal ratio. I sent him a gauge to check deadhead pressures and instead of 1150 PSI he had 2580 PSI. He went from a 7/1 pedal to a 9/1 ratio and used an 1 1/8 bore instead of the 5/8" slave bore..... bigger is not always better.

Has anyone used Hawk or Green Stuff brake pads? What was the cost and did they perform better than standard pads?
