Are you using a brake proportioning valve?
Is it hooked up, or set, properly?
Are your rotors square and true?
Are the calipers mounted square, true, and securely?
Are you using the same brake pads and compounds on both left and right?
What master cylinder (s) are you using?
INEX/ 600 racing legal, or SCCA or some other rules?
If your running ovals, you want to have the left side front brake help "pull" you into the turn.
If your proportioning valve is hooked up wrong, or set improperly, you are likely getting too much pressure to the right front brake. Hence, "pulls to the right".
If your rotors and calipers are not square and true; then it could be part of your problem.
If you are using different brake pad compounds, and/ or manufactures, could also cause problems.
I'm just tossing out ideas here.
Don't have enough info to go on. And don't know what type of track surface and course you are running. I'm sure there are a bunch of folks here that want to help you get up front. If you would like, you can PM me (or anyone) or Email. We'll try to give you the best advice we can.
