Master Cylinder

What Is a Master Cylinder?

The master cylinder is the central hydraulic component in your vehicle’s braking system. When the brake pedal is pressed, the master cylinder converts mechanical force into hydraulic pressure, sending brake fluid through the lines to activate calipers or wheel cylinders. At A-Z Motor Factors Halifax, we supply OE-spec master cylinders designed for safety, precision and long-term reliability.

How a Master Cylinder Works

Inside the master cylinder are one or two pistons, seals and a pressure chamber. When you press the pedal:

• The piston moves forward

• Brake fluid is pressurised

• Pressure travels through brake lines

• Calipers or wheel cylinders apply braking force

A healthy master cylinder ensures consistent braking and stable pedal feel.

Signs Your Master Cylinder Needs Replacing

Replace the master cylinder if you notice:

• Spongy or sinking brake pedal

• Poor or delayed braking response

• Warning lights for brake pressure

• Rear brakes not engaging correctly

• Brake fluid leaking at the cylinder

• Contaminated or dark brake fluid

• MOT failure for hydraulic imbalance

A failing master cylinder is a safety-critical issue and should be replaced immediately.

Why Master Cylinder Fitment Matters

Fitment varies by:

• Bore size
