As brakes wear down, they will produce a squealing or grinding noise. This indicates that the brake discs are approaching their minimum thickness, and will need replacing. Discs are always replaced in pairs, as an asymmetrical braking system can be dangerous, and result in your vehicle pulling to one side while braking. In order to keep the braking system calibrated and in full working order, we recommend also replacing the brake pads whenever you replace your brake discs.

Soft, spongy brakes are an indicator of a brake fluid leak, or that the brake fluid should be changed. When pressure increases inside your hydraulic system, the energy required to compress the molecules in the fluid is emitted as heat energy. Therefore, brake fluid must be able to withstand large temperature changes without changing state. Most available brake fluids are glycol ether based, but liquid mineral oil and silicone fluids are also used. These liquids have a very high boiling point, but are also hygroscopic, meaning that they will absorb moisture from the air over time. This moisture will lower the boiling point of your brake fluid dramatically, meaning that your brake system could cease working entirely above a certain speed. Most manufacturers will recommend changing your brake fluid at least every two years.
