Brake Servo Options

[anonymous-user]

Running a pedal box with brake bias and separate cylinders and reservoirs front and back (on a road car and a racer).

Both light cars with big brakes.

I don't want a sensitive pedal, but wouldn't mind some servo assistance.

Anyone know if there is a nice compact unit that will do the job?

Hi Peter,
Have reduced cylinder sizes on the race car from what they are, and it should help improve feel.

Expecting the road car to need a servo, just looking around upfront.

Do you actually need to adjust the static brake balance on a road going car? I mean, do you realistically expect that the driver will move the brake balance when his mates get in the back, or whatever? It would IMO make more sense to design the brake hardware so that the front and rear circuits run on the same line pressure and then use a conventional tandem master cylinder with a single servo.

LOL, lots to be said for thinking first and buying second Peter.

I replicated the arrangement I have on the race car when building the road car as they both run very similar brakes, albeit the road car is 25% heavier and 30% more powerful...

So I have separate cylinders 3/4" front and 5/8" rear with balance bar in a floor mounted pedal box, which I like, but its not plumbed yet.

May look at the options to plumb it up to a single remote servo...if that's doable?

Its a TVR that will carry a cockapoo in the back from time to time, but he's not big enough to make a difference to brake balance..

Thanks Peter, it's a TVR 3000m. Cylinder sizes were recommended by AP but guess it's a guide. I'll have a play servo free and tweak from there,

I'll let you know how it works out.
