brake master cyls

[r3tracing]

Imca stock car. What size master cylinder bores are you running on the front and rear. We have 7/8 both front and rear and can't get enough front brake. Adjuster all the way to the front and car still acts like it is trying to lock rear brakes on dry slick causing a very loose in feel. Thanks in advance

I run 1" front and 7/8 rear, but I would check that your balance bar is set up correctly, and do you have the same size caliper pistons front to rear?

Yes on calipers. Metric on both

[save the racers]

If you want less rear brake put a 1 inch on the rear.You can get calipers with bigger pistons for the front also.It is a little confusing, bigger m/c gives less brake, smaller caliper gives less brake.We have ran 7/8 front 1''rear with a 2 3/4 front piston caliper, 2 3/8 rear.How much left rear bite do you have.

We had about 140 lbs of bite in it

We had 180 in a camaro that we had to take the rear brake out of.I think cars with some bite in them are more sensitive to rear brake.Have you ever tried not releasing the throttle completely when on the brake?

15 year old driver but we are trying to get him to learn that. We changed rear master cylinder to 1 inch and going to try that.
