3 wheel brakes

[brett4]

3wheel brakes or proportion valves are not allowed in our rules and my driver is a good trail braker. Any ideas to reduce brake pressure considerably?

Put a smaller caliper with smaller pistons on the rf.

[brett4]

rules do not allow that also

Glazed over worn pads on the RF?

[MasterSbilt_Racer]

Orifice in the fitting at the caliper

[MasterSbilt_Racer]

Cryogenic treatment of rotor
Lower friction pad material
Smaller diameter rotor

How small of an orifice would you go with? Would you be concerned with the caliber releasing?? thanks for your time

[MasterSbilt_Racer]

Like .050". It may drag a little. If driver isn't on the brakes very long or hard, should be ok.

Try this so a restrictor doesn't keep the brake on




Red is the restrictor and blue is a one way valve to release pressure around the restrictor.

I have another way that should work way better and be really hard for tech to see or figure it out, but don't want to post here for everyone to see. If you're interested send me a PM.

I don't log in all that often anymore to see PM's so might post you sent one if you do.

What if you were to set the car up for 3 wheel brakes, with the right front cut off, but you also had an extra brake pedal in the drivers tub area, and this extra brake pedal was only used to trigger the rf brake? This extra pedal could be far off to the right side of the drivers footwell. Do you think anyone would actually notice the extra brake pedal? I doubt that anyone, including the tech man would ever notice. Never overestimate the intelligence of an adversary.

I sent you a pm Billet.....thanks for your time

see if you can find a split master cylinder for a Disk/Drum setup that has two different size pistons in the master cylinder and use it for your fronts only. Use the disk outlet for the left front and the drum outlet for the right front. They are not a super common item but can be found.

Use an old-fashioned pull handle like on the old Midgets for the RF brake only? The tech guy probably won't like that either if/once he figures it out.

Make the clutch pedal a brake pedal!
No rules that say anything about shutoff valves on the clutch.
When the switch is open, fluid is bypassed sent to the clutch, when the switch is closed, fluid is sent to the caliper.

Always had an idea to put a small adj valve on each corner.

Sounds like over thinking! Put ball valve in brake line. Hide valve or just play by rules stated and turn on when need 4 wheel and off without foot on brake to 3 wheel

I have put a pop rivet nail in caliper line fitting and put line back on , this worked well , but I guess if they make you jack it up on rt frt to see if break works , your screwed

If you need to hide it from tech that's actually going to look, you need to come up with a way.
