How to Know When Your Brakes Need Replacing

Your brakes are the single most important safety system on your vehicle. Unlike a noisy engine or a flat tyre, brake wear happens gradually — which makes it easy to miss until it's critical.

High-Pitched Squealing

Most brake pads have a built-in metal wear indicator that touches the disc when pads are nearly worn out. The resulting squeal is designed to be annoying enough that you take action.

Grinding or Scraping Sound

If squealing has progressed to grinding, the pad material is completely gone and metal is pressing against the disc. This causes rapid disc damage and significantly increases stopping distance.

Vibration When Braking

Pulsation in the brake pedal or steering wheel during braking usually means a warped disc. This can happen from excessive heat — often caused by riding the brakes downhill.

Pulling to One Side

If the car pulls left or right when braking, a calliper may be sticking or pads may be wearing unevenly. This creates unpredictable stopping behaviour.

Soft or Spongy Pedal

A brake pedal that sinks further than usual or feels soft indicates air or moisture in the brake lines. This is a serious safety issue that needs immediate attention.

Warning Light on Dashboard

Modern cars have brake pad wear sensors connected to a dashboard light. When it illuminates, don't postpone — the sensor is calibrated to give you just enough pad life to reach a workshop.

The Numbers to Know

New brake pads have 10–12 mm of friction material. Replace at 3 mm. New discs have a minimum thickness stamped on them — once they reach that number, they must be replaced rather than machined.
