BRAKE PAD WEAR INDICATOR – 3.3M – GREEN PLUG

A typical vehicle braking system consists of a pair of brake pads, a brake disc
and a brake caliper for each wheel. The pads are fitted in the caliper with their
friction material almost touching the two sides of the brake disc.
When the brake pedal is pressed, hydraulic fluid in the caliper pushes each brake pad against each side of the rotating brake disc. This results in friction which slows down and eventually stops the vehicle.

When you think of the number of times this simple action takes place every day, week, month and year – it’s no surprise that brake pads suffer gradual wear, so they need replacing regularly.
