2. Take away the previous brake pads. Use the 5mm Allen key to loosen the bolts that maintain the brake pads in place. As soon as the bolts are unfastened, rigorously take away the previous brake pads.
3. Set up the brand new brake pads. Align the brand new brake pads with the caliper and insert the bolts. Tighten the bolts till they’re comfortable, however don’t overtighten them.
4. Reinstall the wheel. Place the wheel again into the body and shut the quick-release skewers.
5. Check the brakes. Earlier than you trip your bike, take a look at the brakes to ensure they’re working correctly. Squeeze the brake levers and examine for any rubbing or squealing. If the brakes usually are not working correctly, modify the pads accordingly.
Assessing Brake Pad Put on
Recurrently assessing the damage of your bike brake pads is essential for sustaining optimum braking efficiency and guaranteeing your security whereas driving. Listed below are some telltale indicators and strategies that will help you decide when your brake pads have to be changed:
Visible Inspection
Examine your brake pads visually to evaluate their thickness. New brake pads sometimes have a depth of round 4-5 millimeters. As your brake pads put on down, their thickness will lower. When the pads attain a depth of round 2 millimeters or much less, it is a clear indication that they have to be changed.
Put on Indicators
Many brake pads come geared up with put on indicators that present a easy and handy option to gauge pad put on. These indicators are small grooves or slots machined into the pad materials. Because the pads put on, the grooves turn into shallower. When the damage indicators are not seen or have worn right down to a predetermined degree, it is time to substitute the pads.
Hear for Squealing or Grinding
If you happen to discover a high-pitched squealing or grinding noise once you apply your brakes, it could possibly be an indication that your brake pads are worn and have to be inspected. This noise is commonly brought on by a steel put on indicator coming into contact with the brake rotor, alerting you that the pads are reaching the tip of their service life.
