The most common brake-related services we perform is pad replacement and rotor machining, which go hand in hand. After reading this page, be sure to check out our rotor machining page.
This page describes brake pads and should help readers become more aware of brake pad issues.
Brake pads are simple in nature however, in reality, are made of very complex substances. The pads should be carefully selected to match the vehicle perfectly, which is critical to achieving the maximum stopping power.
At JDM P/L, we use high-quality Bendix pads. We try not to use cheaper variations, as we’ve found they wear through rotors quicker than ideal.
Signs your pads may need replacing:
- Whining, squealing or grinding noises when applying or releasing brakes
- Warning light on the dashboard may illuminate when brakes require attention
- The brake pedal may pulsate
- You may experience your vehicle pulling to one side or the other
- Longer stopping distances than usual
What are brake pads?
Brake pads are made using a combination of different products/ingredients which include functional fillers, friction modifiers, resin binders and fibres. These ingredients are designed to apply friction and dispel heat. They are dark grey in colour.
Pads are located between the caliper and the rotor. The pad clamps the rotor on both sides to slow the vehicle.
Each time the brake is applied, a small amount of the pad is consumed.
Most vehicles use organic or semi-metallic pads. Performance vehicles often use ceramic pads, which are generally four times the cost of organic or semi-mettalic.
How many brake pads do cars have?
Cars have a total of two sets of brake pads (4 per box). That is two per wheel, which is a total of eight individual pads.
How often do brake pads require replacing?
Front pads perform approximately 70% of the work, while rear pads do approx 30%. This additional load means the front pads need to be replaced more often than the back.
Front pads average 60,000km between replacements, depending on driving conditions.
As a rule of thumb, you generally go through two sets of front pads to one rear set.
If your vehicle is exhibiting any of the symptoms describe above, be sure to book a service from a qualified, experienced technician.
We always mache rotors simultaneously (the disc between the two pads), as over time the surface of the rotors can become uneven. Machining ensures there is a flat, smooth contract between the pads and the rotors.
What is breaking in and how does it work?
The bedding-in procedure involves driving the vehicle for approximately 15mins and applying the brakes at different speeds. This is also called heat shrinking the brake compound.
We then test it on the Safe-T-Stop.
This is a service we perform for our clients so they can leave with the brakes bedded/broken in.
