Definitions:

Master Cylinder

The part of a hydraulic brake system that receives input force through a pushrod when the driver presses on the brake pedal. The pistons inside the master cylinder move forward, pressurizing fluid in the brake lines, which connect to the output pistons at the wheel brakes. Hydraulic clutch systems use a single piston master cylinder to activate the slave cylinder.

Hard Spots

Refers to areas within a material or mechanism that are more resistant to pressure or movement than the surrounding areas.

Over-heating

A condition where an engine or device exceeds its normal operating temperature, potentially causing damage or failure.

Out-of-round Drum

Refers to a drum brake component that has become uneven, leading to brake pulsation and compromised braking efficiency.
