4 wheel disc brakes

[astikhossw]

I have a 1984 t-bird that is 2500 lbs with driver and i have strange disc brakes on all 4 with a stock ford master cylinder and i can stab it once or twice at 129 slows down great nothing scary.I use 2 pistons front and 4 piston rear.

Your T-bird master cyl is 21mm or about 13/16".
It will work with 2 piston calipers, but would probably be undersized for a 4 piston front caliper. It also will work better with a low pedal , ratio like 4-1.
If you're using the stock pedal and it had power brakes ,thats about what most of them are.
Getting good brakes is all about balancing pressure with the correct volume ,while getting a comfortable feel for the pedal pressure required.

Tom thanks for the reply, Do you think it will stop ok with the 1" MC. I'm sure its a manual brake set up on the car from the factor.

[Tom Goldman]

Robbie, it should stop ok as long as you don't run out of pedal travel .

Thanks Tom, see you at Cecil.
