Never done a brake pad change before? It's a straightforward job and Haynes will hold your hand every step of the way, thanks to our comprehensive range of Manuals.
First, you'll need to check the condition of your pads. Your vehicle will have them on the front axle and possibly the rear, too. Wondering when brake pads need replacing? When new, brake pads are around 10mm thick. In the UK, they're illegal when they're less than 1.5mm thick, but we recommend you change them when there's 3mm of material left, to ensure you still have maximum braking efficiency.

So you've established that the pads need to be changed. It's important to renew all of the pads on the same axle. So if the offside front brake pads are worn, you'll also need to change the nearside front pads. Never replace the pads on one side of the car. Also make sure you have the right tools for the job before you start – the links below will show you what you need.

On most vehicles, the front brake pads need to be renewed more often than the rears because the extra weight of the engine sits over the front axle. However, if they are fitted (instead of brakes drums and shoes), the rear pads should also be checked and replaced when they wear to the same thickness mentioned above.

Perhaps you have a different issue with your brake system. Is the brake pedal too hard or too soft? Is there a burning smell when you're on the move? Are the brakes squealing and squeaking whenever you use them? Is the brake pedal vibrating? Does the steering wheel shimmy about when you're bringing the car to a halt? These symptoms could indicate that something is wrong with your pads or discs.

Maybe you have a seized brake caliper, which would explain the burning smell or that 'stickiness' you feel when setting off in the car from a standstill.
Learn about the different types of caliper available, and which will be fitted to your car.

If the brake caliper is beyond repair, you’ll need to replace it. Find out how to do that here.
Got brake drums and shoes? Haynes can help you with those, too.

Changing the brake shoes is a slightly more involved job than replacing brake pads, but Haynes has all the information you need.
