Brakes
The Braking System
Braking systems are complex and involve a number of different components, including:
Brake Discs
- The brake disc is a device for slowing or stopping the rotation of a wheel while it is in motion
- Brake discs are sensitive components and come under significant stress during braking
- For your brake pads to work at maximum efficiency, your brake discs need to be in perfect condition
- If the disc is deeply scored, glazed, cracked or rusty, replace them immediately
- You must always replace both discs on the same axle to avoid unequal braking
- Hylton recommend that discs are checked each time the pads are changed
Brake Pads
- The material which the pads are made from is softer than the discs and will therefore wear out more quickly
- Worn pads can damage the brake disc
- Have your brake pads replaced when the thickness of the material is worn down to 2mm
- Brake pads should be replaced on both wheels on the same axle to prevent asymmetrical braking
Brake Drums and Shoes
- This is another type of brake where the friction is caused by a set of brake shoes pressing against a rotating drum-shaped part called a brake drum
- When brake drums are replaced, the brake shoes, wheel cylinders and springs should also be replaced because they are subjected to the same type of pressure as a brake pad
- The brake shoes should be replaced as soon as the thickness of the lining is less than 1.5mm
Brake Fluid
- Braking components are linked by a series of hoses and pipes containing brake fluid
- Brake Fluid is a vital part of the braking system and the vehicle’s anti-lock braking system
- Over time, brake fluid deteriorates. Unfortunately, it is also one of the most overlooked vehicle fluids
- It should be regularly changed at least every two years to ensure that the braking system is not affected
- If it falls below the MIN level in the reservoir (or if the brake warning light comes on), brake fluid should be added up to the MAX level.
- If your brake fluid needs topping up regularly, you should have your braking system checked by your local Hylton Dealership service department for possible leaks.
What are the signs there is a problem with my brakes?
- The brake warning light comes on if the brake fluid level is too low or the pads are badly worn. (The brake warning light also comes on when the handbrake is applied).
- The brake pedal is stiff. If you have to press hard to brake it may be caused by a failure in the servo assisted braking unit, hydraulic pipes, wheel cylinders or callipers.
- The brake pedal is too soft. If the brake pedal becomes ‘spongy’ or has no resistance and you have to ‘pump’ the pedal to brake, then it’s a clear sign that there is a serious fault in the hydraulic system.
- The car pulls to one side. If the car is pulling to one side it may be that a wheel cylinder or a calliper is seized up or quite simply a tyre may be under-inflated. Worn shock absorbers can cause the same effect.
- The vehicle ‘judders’ when braking. This indicates a problem with the discs, the linings or that one of the brake parts is loose or broken.
- Vibration. On braking, the brake pedal, steering wheel and sometimes the whole vehicle start to vibrate: the brake discs are probably faulty, or there is a loose part or excessive play in the front or rear suspension.
If you experience any of the above, contact your local Hyltondealership as soon as possible to arrange for a check of the condition of your braking system.
Hylton Recommends:
- As braking components wear over time it is important to get your braking system checked and maintained on a regular basis.
- You get your brake fluid replaced every two years; normally this would happen at your vehicle’s scheduled service.
- Don’t forget that any braking system is only really effective with shock absorbers and tyres that are in good condition.
- Your brakes are checked by the professionals. Our Peugeot technicians know your vehicle’s braking system inside out so you can be sure they will provide you with the right advice.
Why are brakes so important?
The braking system is your vehicle’s most important safety feature, enabling you to slow down, stop and stop quickly in an emergency. Like all components, your brakes and braking performance will deteriorate over time, but because it happens gradually, many people may not notice the difference.
It is a legal requirement that your braking system is performing correctly and your brakes will be tested as part of your MOT. If the braking system is not up to standard your vehicle will fail.
It is therefore vital that your braking system is regularly checked and maintained to an optimum level, ensuring your vehicle is safe and to avoid potential costly repairs.
