How to Fix a Car Shaking When Braking
Vibration through the steering wheel or pedal when braking is almost always caused by warped brake discs. It is important to have this inspected promptly.
Likely causes
- Warped or scored brake discs
- Worn brake pads
- Sticking brake caliper
- Loose wheel nuts
- Worn wheel bearings
- Tyres out of balance
Step-by-step fix
-
1
Note when the shaking happens
Does it happen when braking at high speed only, or all the time? Vibration only during braking points to brake discs or pads.
-
2
Visually inspect the brake discs
Look through the wheel spokes — you should see a smooth, shiny disc surface. Deep grooves, rust channels, or a clearly thin disc means they need replacing.
-
3
Check the wheel nuts are tight
Use a torque wrench or ask a tyre shop to check. Loose wheel nuts cause vibration and are dangerous.

4
Have the brakes inspected by a mechanic
Brake disc and pad replacement is essential maintenance. Do not delay — failing brakes are a serious safety risk.

5
Check tyre balance
If the car shakes at certain speeds but not when braking specifically, tyre balance or alignment may be the issue. Ask a tyre shop to check.
