anyone block off their RF brake, either valve or some other means, and do u think there is an advantage for shuting that brake off? Just wondering if this was a good idea to help get around faster

It's a good crutch if you having problems getting the car to turn on entry.

It does help if your rules allow it. In our Late Model days we didn't even run a rotor on the RF.

I have seen guys grind the middle of there pad on the rf never done it myself or used a shutoff. But most rules dont allow a shutoff so grinding the pad whould be best Hey mod05 that track ready yet??

You can also run different sized calipers (pistons) on the front so you have less breaking force on the front right. Grinding pads for the RF would reduce things even further. Don't run mixed pad compounds as you'll get unpredicatble results as they heat up. Most rules require 4 wheel brakes but we have a valve installed for those open races that will allow.

The times I might consider turning the RF off would be early in the night (qualifying or for a dash) when things are tacky and most of the braking is in the rear already.

I used to always run with the RF shut off with a cheater valve because I couldn't get the car to turn and rotate if I ran 4 wheel brakes. To solve the problem, I installed high quality brake pads, not the junk I was using from Kragen and Chief Auto Parts. I use the good quality pads all the way around. I use the Brakeman pads, but there are Hawk, Performance Friction, Wilwood, Gator and some of my friends use the pads from Speedway. I can drive the car, now, with 4 wheel brakes and it rotates like it has the RF brake shut off. Don't overlook the shape of your rotors. These need to be in good condition to take full advantage of the new stopping power. Lastly, don't be concerned about the aftermarket pads eating up your rotors. I was worried about this but haven't seen it to be an issue.

You can use a drag racing line-lock to shut off RF. Just plumb it into the line coming out of the master cylinder,it can be hidden in the cockpit. You have to run it backwards from what they do on a drag car so it blocks the fluid from the master-cylinder.Then wire it to a toggle switch,you have to then manually squeze in the caliper before turning on the solinoid.Then if you need RF brake you just turn off and pump brakes.Make sure you dont pump brakes when car is setting and then turn on switch or your brake will lock up.
