Hi all, I am installing my brakes, I have 1985 lotus esprit turbo brakes all round
fronts are single piston 2¼ inch (57mm) and rears are single piston 1¾ inch (45mm) with integrated handbrake mechanism
Balance bar mechanism replaced (for testing) with a solid shaft so I can connect front or rear for testing and to check pedal travel , pedal ratio is 5 to 1 floor mounted.
Connecting the Rear mc only with both 0.625 and 0.7 mc gives a nice “feel” with a solid stop (no flexing) no too much travel and not too much pushing from my leg
However connecting the fronts only I feel a lot of flex, not a real solid stop in pedal movement but pedal travel is almost 5-6 inch (tested with 0.625/ 0.7 /0.75 without much difference)
Calipers have new piston seals and sliding pins have new seals and grease and no leak
Is it possible that the calipers go back too much after releasing the brake pedal? And because of this need too much pedal travel? (sticking piston seals)
How much of a gap (feeler gauge between disc and pad) is normal / ok for sliding pistons so I can test if they go back too much ?
Thanks, Rick
