Brake Disc
Frequently Asked Questions - Brakes

Brakes - General
Q. I get a vibration every time I apply the brakes. What causes this?
A. Most likely cause is warped or heavily worn front brake discs. Replace the discs. You should also replace the brake pads, as they will have worn with your old discs.

Q. What is causing my car to pull to one side when I brake?
A. This could be a number of causes. Check the following:
1. Air or water in the brake fluid - bleed the brakes through with new fluid to remove any air or moisture
2. Brake caliper sticking on slider - remove the caliper, clean and grease the sliders. Ensure rubber boots are OK
3. Sticking brake caliper piston - remove the brake caliper and check the piston moves freely. If not, replace or rebuild the caliper
4. Perished flexible hose - check the condition of the rubber flexible hoses and replace if in doubt. Rubber hoses perish and 'close up' with age.

Q. My car pulls to one side for a while after I have applied the brakes. What causes this?
A. This is most likely a sticking front brake caliper. This will overheat your brake discs and pads and cause damage. You need to replace the offending caliper, or rebuild it. First though, check that it is sliding properly on its mount, as you may cure the problem by simply removing the caliper and cleaning/greasing the slider.

Q. I get a vibration every time I apply the brakes. What causes this?
A. Most likely cause is warped or heavily worn front brake discs. Replace the discs. You should also replace the brake pads, as they will have worn with your old discs.

Q. If I pull on my handbrake at speed whilst turning the wheel, my car spins round 180 degrees. Why?
A. Give yourself a pat on the back. You have mastered the handbrake turn.

Performance Brake Pads
Q. What are 'performance brake pads'
A. Performance brake pads are designed to work under more demanding conditions than the pads supplied by the manufacturer. This may be in terms of how well they slow the car, how well they stand up to prolonged braking or both. If you regularly drive in a very 'spirited' way, your standard pads may overheat and go brittle.

Q. Do I need performance brake pads?
A. Generally, the brakes fitted to a modern Peugeot (including older 106, 205 and 309 models) are very good, especially on GTi models. If you feel that your brakes are not performing as well as you would like, it may just be that the standard components are worn out.

However, if you do place a heavier demand on your brakes due to your driving technique, or if you use the car for track days etc., performance brake pads are the first brake modification to try. You normally only need them on the front of the car because the rear brakes do very little work. This is because the weight of your car transfers toward the front under braking.

Be careful to check for pad wear regularly on upgraded pads though, as they can often wear out more quickly due to the different type of compound used.

Performance Brake Discs

Q. What are performance brake discs?
A. Performance brake discs are designed to work under more demanding conditions than the discs supplied by the manufacturer. This may be due to better quality metal, construction, design or larger diameter. Here are some common terms associated with performance brake discs:
- Vented: the disc is hollow with internal vanes that dissipate heat more efficiently
- Cross Drilled: the disc is drilled through from face to face to help dissipate heat and gases
- Grooved: the disc face has a number of grooves machined in to dissipate gases and help de-glaze the brake pads
- Knackered: the disc faces are rutted and grooved due to the fact that you have worn them out

Q. Do I need performance brake discs?
A. Generally, the brakes fitted to a modern Peugeot (including older 106, 205 and 309 models) are very good, especially on GTi models. If you feel that your brakes are not performing as well as you would like, it may just be that the standard components are worn out.

However, if you do place a heavier demand on your brakes due to your driving technique, or if you use the car for track days etc., performance brake discs are a sound investment, especially if the standard items are due for replacement anyway. You normally only need them on the front of the car because the rear brakes do very little work. This is because the weight of your car transfers toward the front under braking.
