Race Car Brake Set Up For Track Day, Rally, Drifting, Performance, Saloon, Hot Hatch - Obp Tech

Author : Grant Loc


Hello Race Drivers.

I am passing this information on to you because it is a common theme I and my team are asked about time and time again. This guide is perfect for Track Race Cars, Track Day Cars, Rally Cars, Drifting Cars, Performance Cars, Saloon Racing, Hot Hatch Racing.

Fitting Your Track Pro Race Car Bias Pedal Box:

Firstly if fitting a pedal box to a 'road'/saloon type car you will need to remove all your standard pedal box system and its ancillaries such as the servo and ABS systems etc... However, before you do this either measure or take photos of the positions of the standard brake pedal so that you know you fit your new pedal box in the right place. These photos are helpful because you may need to refit some items as some cars use the pedal box to support the bottom of the steering column.

Fitting Master Cylinders, Plumbing In and Bleeding Brakes:

When fitting the cylinders first it will be easier to build the pedal box assembly up out of the car and the fit the whole unit in to your car in one piece only leaving the plumbing up of the brakes, clutch and the fitting of the throttle cable.

The normal set up and start set up master cylinder guide is.

Sizes for the master cylinders are:

0.750" Clutch

0.750" or .700" Rear Brakes

0.625" Front Brakes

The front brakes have a smaller bore master cylinder so that they will always have slightly more pressure when the bias bar is in the 50/50 position.

The full set up of the bias bar set up is explained in one of my other articles.

When plumbing the brakes in this will be one of the most time consuming part of the job. At this point you will require a rethink of the plumbing of the system and it will most probably work easier to fully re-plumb the whole system as standards car system can be complicated with dual line systems etc.

It is best to fit new brake lines in Track Race Cars, Track Day Cars, Rally Cars, Drifting Cars, Performance Cars, Saloon Racing, Hot Hatch Race cars.

The easiest way to plumb the bias pedal box in is as follows:

Front brakes - Single line up to a 4 way t-piece and the split into two lines of equal lengths to each front calliper. In this t piece you will install an inline BRAKE LIGHT pressure switch this will save lots of hassle and time mounting the standard switch.

Rear brakes - Single line through a hydraulic hand brake (if fitted) to a t-piece and the split into two lines of equal lengths to each rear calliper.

Clutch - simply a single line to the slave cylinder in/or on the gearbox.

The pressure lines you use (either hard line or flexible) are again down to personal preference, although where any flexible lines are used they need to be done in high quality Motorsport spec braided lines.

On the cylinders you will find that there are two different size threads, these are 3/8" UNF (PRESSURE) and 7/16" UNF (FEED) threads.

The 3/8" UNF fitting is the pressure feed out to the calliper or clutch and the 7/16" UNF is the fluid feed into the master cylinder.

This guide is perfect for Track Race Cars, Track Day Cars, Rally Cars, Drifting Cars, Performance Cars, Saloon Racing, Hot Hatch Racing.
