How to Check if the Job Was Done Properly
Once your brake pads and discs have been replaced, it’s important to ensure the job was done properly:
- The car should brake smoothly and quietly. There should be no vibrations or grinding sounds.
- The brake pedal should feel firm and responsive.
- Ask the mechanic to show you the old parts—most reputable garages will offer to show you the old components as proof.
- Brake fluid should be topped up and bled if necessary.
- You should receive a written invoice detailing the work done, parts used, and any warranty offered.
Tips for Drivers for Pads and Discs Replacement
- Replace pads and discs in pairs: It’s always best to replace brake pads and discs on the same axle (front or rear) to ensure balanced braking performance.
- Get a quote upfront: Many garages offer fixed-price brake services. Always ask for an upfront quote before agreeing to the work.
- Book regular brake checks: It’s wise to have your brakes checked during your MOT or annual vehicle service.
- Drive gently: Avoid harsh braking, particularly in stop-start traffic. Gentle driving can extend the life of your brake pads and discs.
Additional Considerations
When booking a brake replacement, consider the following:
- Warranty and Guarantees: Ensure that the parts come with a warranty and that the work is guaranteed. Most reputable garages provide warranties on parts and labour.
- MOT Considerations: If your brake pads or discs are found to be worn during your MOT test, your vehicle will fail, and you’ll need to have the parts replaced before retesting.
By staying on top of brake maintenance, you’ll ensure your vehicle remains safe and efficient on the road. Remember, regular checks and timely replacements are essential to keeping your braking system in top condition.
