Brake Optimal Performance

What not to use on your brakes after the bedding in process, 

  • Car Brake Cleaner
  • Detergent
  • Bike Cleaner
  • Soap
  • Any other bike cleaners
  • Isopropanol
  • Acetone
  • Jet Wash
  • leaving moisture to sit on your brakes for days is not recommended
  • when riding the brakes will dry from heat, washing and putting your bike away with wet brakes will contaminate pads and can also damage seals – which may cause sticky pistons )
  • Resin pads will start to deteriorate with moisture and the compound may part from the backplate.
  • Sintered brake pads can rust.


  1. Remove the calliper from your fork/frame and retract piston with the correct tool.
  2. Extract old brake pads and clean inside calliper with a dry rag removing any dirt, moisture, etc.
  3. Pump the pistons out (not too far) and clean around the pistons as much as you can, adding a little oil to pick up dirt around the seals and piston. Carefully push pistons back into the calliper and clean with a dry rag. Repeat this process until pistons are moving free and equal.
  4. Sram brakes/Avid brakes – All brakes can suffer from sticky pistons, so make sure that the pistons are fully retracted before adding new pads. You may need to bleed a small bit of oil from the reservoir to get the pistons fully retracted, as mineral oil and brake fluid can expand under heat.
  5. Bleeding your brakes regularly is very important for optimal performance.


  • Resin
  • Multi compound Kevlar with Copper
  • Sintered
  • Ceramic

Resin brake pads – These pads can make bad brakes feel like they work. Resin is incredibly soft and will bite almost instantly making them easy and quick to bed in, but can also mask a weak brake. This can cause premature pads life and uneven braking.

Multi compound Kevlar with Copper – This is also a soft compound. The resin is mixed with kevlar and copper fibres to help brake fade and longevity, compared to resin pads, a great all-round compound.

Sintered – A full metal brake pad. This brake pad will need the brake to be working to optimal performance. If your brakes are not looked after, with a fresh bleed and pistons moving freely, you will struggle to bed this brake in. Uneven piston movement will cause one side (the weak piston) to glaze over, this will cause vibrations ending in horrific screeching noises. Sintered brake pads are quiet when bedded in properly. Longevity with sintered brake pads is great for winter riding.

Ceramic – The light bite until hot. Ceramic sit between sintered and multi-compound. Perfect for racing and road bikes as the initial pull from the lever will not lock the brakes, making you quicker in the turns. They are silent under braking when bed in properly.

All compounds have their benefits, but if you do not look after your brakes the brake pads will not work properly, Brake maintenance is essential and cleaning and prepping your brakes is overlooked, it should be the most important part of your maintenance schedule.

99% of the time the problem is the brakes, not the brake pads.

Bedding Gorilla pads in


  1. On a gradual descending slope, drag each brake for 20-30 seconds, alternating between front and rear. Repeat 3-4 times.
  2. On a hill or steep descent, engage the lever and drag the brakes for 15-20 seconds slowly increasing lever pressure until the bike slows almost to a complete stop. Repeat 3-4 times.
  3. The front pads will generate more heat than the rear. Once bedded in swap front to rear to create ultimate stopping power.
