- Bosch QuietCast brake pads use a friction material formulated and tested by Bosch engineers
- PTFE and rubber coated hardware reduces vibration and noise and keeps the pads from binding to the caliper
- Powder-coated backing plate prevents rust and corrosion
- Protective transfer layer helps extend pad and rotor life

Front pads wear a little with every stop. A squeal or grinding noise, longer stopping distances, or pads that look thin during a tire or brake service can mean they are worn. Those signs alone don't prove the pads are at fault, since a sticking caliper can produce them too, so track down the cause before you replace anything.
