Brakes and related components
- Brake circuit
- Brake control system
- Discs, drums, calipers and pads
- Brake assist, anti-blocking or regulation system
- Service brake
- Parking brake
Brake Fluid Reservoirs
- A low level of brake fluid will lead to longer braking distances, reduced braking performance or even complete braking failure.
- If the tank or its cap are in bad condition, moisture or air can contaminate the brake fluid. The water evaporates when braking leading to more air bubbles and this air compromises or completely eliminates the braking effect.
- If the brake fluid is excessively old, the same effect can occur.
- The braking capacity will be reduced or compromised in the event of a leakage.
Brake Pipe Hose
- Braking capacity may be severely compromised if there is a leakage (it could result in an imbalance or lack of brake power).
- Brake failure may occur, as well as a sudden loss of braking capacity, if there are signs of oxidation, wearing or cracking.
- A brake imbalance may occur if the pipe is pinched or damaged.
- It may be difficult to stop the vehicle on slopes if the cable is seized or if there is excessive command free play.
- There is a risk of sudden cable rupture and a loss of efficiency if these components are in a very bad state.
Service Brake Pedal
- Pedal movement may be affected leading to a decrease in control precision (delay, hard pedal) and longer braking distances if the pedal isn’t securely fitted or there is excessive pedal play.
- A heightened risk of foot slippage and loss of control if the condition of the support surface is below standard.
Parking Brake Control
- Inability to lock the parking brake resulting in an inability to immobilize the vehicle.
- It takes longer to engage, signifying a problem of cable adjustment or the wearing down of the brakes.
Brake Discs and Drums
Wheel Caliper / Cylinder
- Loss of efficiency and longer braking distances if there is a leakage.
- Lack of efficiency on a wheel or risk of a wheel locking (risk of spinning or longer braking distance) if it is damaged or not securely fitted.
Brake Pads/ Linings
- Reduced braking efficiency and longer braking distances may occur where there is excessive wear.
- There is a heightened risk of spinning and longer braking distances if pads are damaged on one of the wheels.
Brake Assist System
- The braking capacity will be compromised if there is leakage leading to an imbalance or lack of braking power.
- Reduced braking performance and longer braking distances if it malfunctions.
Anti-Lock Braking System
- There is a heightened risk of spinning and longer braking distances in emergency situations if any of the assistance systems do not work well.
- Braking distances will be increased if efficiency is excessively low (when traveling at 90 km/h a vehicle that operates below the recommended threshold value will need 30 extra meters to stop).
- A loss of control might occur if the right and left brakes are imbalanced.
- If the efficiency is excessively low, the vehicle could accidentally roll away when left unattended.
- Hill starts may be difficult.
