Brake Recommendations Please - ZR-1 Net Registry Forums

Rockauto has HD loaded calipers pretty darn reasonably. Looks like that's your best bet for making it easy, and it would probably come with new retaining pins, which in my world are wear items and seem to have dried up (at least there). In the old days you would hone the cylinders and clean everything up, maybe replace the pistons, new seals & pads and off you go. Nowadays you just replace with reman stuff.

Russ has the tech on the stainless lines, I found they gave a 5% improvement where a 20% was hoped for, but they do give worthwhile robustness and your stock lines are almost certainly aging out. Plus if you do juggle various wheel sizes etc they'll be more immune to a stray tire rub.

The 91 pedal ratio with the stock M/C and front caliper piston combo will never give what I would call a firm brake pedal. Brake upgrades usually just increase the heat capacity (ie for track use), the stock brakes are perfectly able to hit ABS and that is the real stopping power indication. You could argue that C5 parts are more readily available for future maintenance but I've not had a problem with C4 J55 parts - yet.

Cheers,
