I will rebuild my caliper with o-ring! and i would like to know if anyone try to improuve o-ring piston!?

Well I think I understand you. You want to make a new piston?
VBP supplies a Kit with all the parts for o-ring conversion.

i know and i will take a kit to VBP but it would be grat to know if some folks modified their piston to have a better heat shield between pads and caliper ! and if remove spring inside caliper help to prevent heat to move from disc to caliper!?



Ps: i install an hydroboost so my next ennemy is heat!

For heat control, also consider a small inline fluid cooler in the return line to the pump, after the two return lines have 'T'ed together.

I installed one, and my power steering fluid stays nice and cool even with the Hydro.

It's good that you're planning a cooler for the fluid, but the radiator cooler might be a problem. Routing the return from the two units to the radiator and then back to the pump might add too much resistance to the fluid's path. The performance and efficiency of the Hydro depend on the systems flow speed back to the reservoir. I can't say for sure, but I personally would not attempt it on mine.

I used a small cooler, mounted on the inner fender of the driver's side.

You want to keep slight contact between the pad and the rotor surface at all times. Any gap will give you a very low pedal each time you step on the brakes.

Unless you're running a 100% race set up, the stock calipers do not suffer from heat.

You don't need the springs with o-ring pistons.
