the piston is moved forward in the cylinder via the brake lever. The piston is returned by a spring against the piston when lever force is removed. There are two holes, called ports, in the master cylinder which allow fluid to enter the cylinder. These are called the fluid inlet port and the compensating port.

As a brand of ZF Aftermarket, TRW designs braking systems for over half the world's vehicles, building much of the original equipment they are fitted with when they roll out of the factory. And we've been doing it for nearly 100 years.

It is the seals fitted to the pistons inside the master cylinder, these are the seals that seal the cylinder and create the pressure in the cylinder when the brake pedal is depressed, the pressure created here, in turn, is pushed into the brake pipes to activate the brake calliper pistons and rear brake shoes cylinders ...

The primary seal allows brake fluid from the reservoir to flow into the brake hosepipe when the brake lever or pedal is pressed. The secondary seal prevents brake fluid from moving to the other side of the cylinder when the brake lever is activated and acts as a spring retainer.

Girling master cylinders have been a common fitment on competition cars for 50 years they feature an 7/16"-20 inlet port and can be either used with remote-mounted reservoirs or can accept direct mount reservoirs whith a suitable 7/16-20 outlet. The fluid outlet is 3/8"-24.

The tandem master cylinder contains two piston assemblies; one for each axle set or diagonally located pair of brakes. Each piston assembly has two lip seals mounted in grooves on the pistons. The rearmost piston cup or lip seal holds the fluid in the master cylinder and against the back of the forward cup.

Pressure to the primary (first ) port comes from the primary (first) piston in the master cylinder. The secondary port would therefore be the second port with pressure supplied by the secondary piston.

Master Cylinder are made by Pressure Die Casting. The material mainly used is an Aluminium Alloy known commercially as AC2A. Though the final product is like a hollow cylinder the aluminium die cast is not hollow rather a solid block generally weighing in t...

The bigger the master cylinder is, the more fluid you get but less pressure at the caliper. The smaller the master cylinder is, the less fluid you get but you'll have more pressure at the caliper. Think of it like putting your thumb over the end of a water hose.
