FAQ
How often should I replace my brake pads?
Brake pads typically last between 40,000 to 100,000 km, depending on driving conditions and habits. Regular inspection every 10,000-15,000 km can help determine when replacement is necessary.
How much can I save by replacing brake pads myself?
DIY brake pad replacement can save up to 50% compared to professional services. In South Africa, the average cost for professional replacement is R800 to R2000 per axle, while DIY costs can range from R400 to R1000.
What are the signs that I need new brake pads?
Common signs include squealing or grinding noises when braking, reduced braking performance, and a brake pedal that feels different than usual. Some vehicles also have brake pad wear indicators that will make a noise when replacement is needed.
Can I replace brake pads on just one side of the vehicle?
It’s recommended to replace brake pads in pairs (both wheels on the same axle) to ensure even braking performance. Replacing only one side can lead to uneven braking and potential safety issues.
Do I need to replace the rotors when I replace the brake pads?
Not necessarily. Rotors can often be resurfaced if they’re still within specification. However, if the rotors are worn beyond the minimum thickness, warped, or scored, they should be replaced along with the pads.
