Types of Brake Pumps or Master Cylinders and Their Components

XPURA is a stable one-stop truck parts wholesaler with 15 years of experience, supplying quality brake master cylinders and spare parts to over 100 countries worldwide.

The brake pump, also known as the brake master cylinder, is the core component of a truck’s hydraulic braking system. It converts mechanical force from the brake pedal into hydraulic pressure to actuate wheel brakes. There are two primary types: single-chamber master cylinders and tandem (dual-circuit) master cylinders. Tandem designs are widely adopted on modern trucks, featuring two independent hydraulic circuits for safety. If one circuit fails, the other can still deliver partial braking power.

Key components of a master cylinder include the cylinder housing, primary and secondary pistons, return springs, sealing cups, fluid reservoir and pushrod. Worn seals, internal corrosion or fluid leakage are common faults that cause soft brake pedals and reduced braking efficiency.

XPURA’s wholesale brake master cylinders are manufactured for heavy-duty, medium and light trucks. We provide reliable braking system components for global distributors, repair garages and fleet operators. For durable truck brake pumps with stable supply, XPURA is your trusted wholesale partner.
