About brake servo repair kits

Brake servos and air packs boost driver pedal effort, using air or vacuum to apply hydraulic brakes on light and medium trucks and buses.

When to replace

A hard pedal, hissing under braking or fluid loss into the servo point to worn diaphragms, seals or valve parts.

What's in the kit

Repair kits restore servo diaphragms, piston seals and control valve rubbers so the unit returns to full assistance. All 6 brake servos lines are manufactured by Pitchline Engineering in an ISO 9001 environment in Pinetown and supplied from our Pinetown branch across South Africa.

Brake Servos questions

What does a brake servo kit include?

Typically the diaphragm, piston seals, O-rings and control valve rubbers for the specific servo or air pack.

What causes a hard brake pedal on a truck with an air pack?

Often a leaking diaphragm or worn seal inside the air pack reducing assistance; a repair kit addresses this.

Are ManuMark brake servo kits made in South Africa?

Yes. The components are manufactured by Pitchline Engineering in Pinetown.
