Brake Problems

Home » Brake Problems

Brakes give plenty of warning before they fail, and the warnings are easy to read once you know what each one sounds and feels like. This is also the system where the tolerance for putting a job off is lowest.

What Usually Goes Wrong

Squealing and grinding

Wear indicators, glazed pads, and the metal-on-metal grinding that means the pads are already gone.

Soft or sinking pedal

Air in the lines, a failing master cylinder, or a fluid leak — all of which need attention before the next drive.

Pulling and uneven braking

A car that veers under braking usually has a sticking caliper, a collapsed flexible hose or contaminated pads on one side.

Vibration when braking

Pulsing through the pedal or steering wheel at speed, and why ‘warped discs’ is usually the wrong explanation.

Before you start work on any car

Chock the wheels, use axle stands rather than a jack alone, let hot components cool, and disconnect the battery before touching wiring. Brakes, steering, fuel lines, airbags and the orange high-voltage cabling on hybrids and EVs can cause serious injury or death if handled incorrectly. If a job is beyond your tools or experience, stop and book a qualified mechanic — there is no shame in it and it is always cheaper than the alternative.
