Anyone have issues with Brake Bias when running RL Calipers? I saw a thread on the TL side but wasn't sure about the CL's.

If so, is there anyway to bring the brake bias somewhat back to normal?

Thanks,

No doubt that the bias will be shifted up front more. There is no BBK we can use for the rear to even out the bias.

I don't think Brake bias will be an issue with RL Calipers or Stoptech BBK. Even if bias is slightly changed don't think it will matter unless you are using car on road courses.

Don't really need a rear BBK to even bias. You could build custom bbk.

I eventually plan to run new Brake lines with an adjustable proportioning valve I can adjust from cockpit.

I am more concerned with how abs will react to lower weight, etc. Might want to get rid of it.

Stoptech builds their kits specifically for stock proportioning. Just beef up the rear pads.

A production fwd car with 60/40 weight distribution, would need front brakes with 50% more torque output than the rear brakes.

There are other things to consider when determining Brake bias. Tire traction, center of gravity, wheelbase, weight transfer, Brake pad material, rotor diameter, caliper piston diameter, etc.

Do you know the bore and length of a RL master cylinder vs our stock master?

No, but shouldn't be too hard to find with a little research.

Yea I am looking at it right now and the design looks totally different then our master. Is our master 2 pistons? Wanted to see if we could swap the RL master onto our car to help with the lack of fluid we would have in our system to operate the calipers correctly. Has anyone tried this before with success?

Looks like same 1" bore for both.

Is it going to be the big of a problem when it comes to running bigger calipers on a stock master cylinder?

Our XLR8 Stoptech Touring BBKs are designed to not throw off the stock brake bias. I'm not sure about RL calipers though, I don't know how they would impact brake bias. Since they are designed for a different car, they might throw it off.

On a CL, highly unlikely. Civics install RL Calipers and use Integra or rsx cylinder.

My calipers operate correctly with the original master. The pedal is a little soft but that can be fixed with SS brake lines.

And I've engaged ABS before with the BBK, seems to work fine to me.
