The Braking system is one of the most important safety related elements in cars. It is mandatory to check and service the braking system every time you carry out a general service for your car or if you feel the brakes are not effective.
This will include checking the brake fluid levels in the brake fluid reservoir, opening the brake calipers to inspect the brake pads and opening the brake drums to inspect the brake shoes.
When are you likely to need a brake overhaul?
- Screeching noise whilst braking
- Shuddering of the vehicle at the time of braking
- Reduced braking effectiveness
- It is also advised to check your brakes every time you prepare to embark on a long drive or if you’re using your car after it has been left idle for a long time.
Following is a case study of a Chevrolet Beat – during initial inspection, it was determined that there was a screeching noise and a shuddering sensation from the brakes when pressing on the brake pedal while driving. The customer had installed new brake pads during the previous service, but the poor condition of the brake disc meant that the disc had worn out the brake pads unevenly and caused damages to its surface. Also the circular edge of the brake disc was completely rusted.
Cartisan procured original OE brake pads and brake discs and arrived at the customer doorstep. The following is a step by step account of the brake overhaul for the front wheels.
The car is lifted up using a hydraulic jack
The wheel nuts were unscrewed and the wheels were removed.
The brake calipers are removed from the brake discs and the brake pads that are fitted to the calipers are removed as well.
It can be seen that the brake pads are cracked and worn out unevenly
The difference between new brake pads and worn ones are shown here
The brake disc or the rotor is detached from the wheel hub. In this case a little more work and anti rust spray was required as the rusting on the disc made it difficult to remove it from the hub.
The difference between new brake discs and worn out rotors are shown here. Worn out brake discs usually have scoring marks or scratch marks on the face of the rotor. Also there would be a step in the surface of the rotor, the edge being at a higher level.
The new rotor is mounted on the wheel hub and is screwed in place.
After this the caliper is mounted back onto the rotor, the brake pads are slotted in place and the caliper is fitted to the brake disc. The caliper bolts are also greased.
The wheels are then mounted onto the wheel hubs and screwed in place.
