Compatibility

Match the exact caliper model and pad shape to the list below. On Orion HD-M735 and Gemini HD-M530, these pads fit the rear two-piston caliper only. HD-E720 and HD-E725 use a different four-piston pad shape and are not compatible with this listing. These pads are supplied at 4 mm thickness. Gorilla Brakes confirms use in the listed P21.11 / E11.11 applications originally specified with 5 mm pads.

E-bike recommendation

Sintered pads can be used on compatible e-bikes when permitted by the brake and rotor manufacturers. Sintered pads generate a lot of heat, which can transfer to the caliper faster than with other compounds in our range. For high-heat applications, Gorilla Brakes recommends the Enduro Pro and Factory Racing compounds.

Rotor compatibility

Use Sintered pads only with rotors approved for metallic or sintered pads. Do not use them with rotors marked “resin pads only”.

Rotor diameter and thickness must meet your brake manufacturer’s specifications. Check rotor condition and minimum permitted thickness before fitting new pads.

Compound performance

Sintered

Strong wet-weather braking and durable performance for cold, wet and muddy rides. A good choice for winter commuting and everyday riding in poor weather.

Published results describe the tested pad, rotor and brake setup. Graph values are approximate; actual braking and wear depend on your setup and riding conditions.

Compound testing

Sintered: braking power

These pads use a steel backing plate.

The graph compares pad compounds and backing-plate configurations, all tested with the Shimano XT RT86 rotor.

Why some curves stop earlier

Each test run stopped when the measured caliper temperature reached 120°C, the stopping threshold used to protect the piston seals in this test setup. The horizontal axis shows rotor temperature. Sintered’s shorter curve means the caliper reached the limit at a lower rotor temperature.

About this test

This chart compares braking power for bedded-in pads, all tested with the Shimano XT RT86 rotor. The horizontal axis shows rotor temperature (°C); the vertical axis shows braking power (W). Each curve represents the compound and backing-plate configuration named in the selector. Compare curves within their plotted ranges; no result is shown beyond the end of a curve.

Follow the Gorilla Sintered curve. Its highest plotted output in the Shimano XT RT86 rotor comparison was approximately 1,020 W. Values are approximate reconstructions from the supplied graph. This result describes the tested pad and rotor setup, not a maximum power rating or a fitment test.

Test context: All pads shown can be good choices for their intended use when correctly matched to the bike and rotor, installed and bedded in. A lower or shorter curve does not by itself make a pad a poor everyday choice. Real riding temperatures depend on the route, total load, braking technique and setup; this test does not establish a temperature limit for the average rider. Rotor choice can substantially affect braking power, but these results apply to the tested combinations. This comparison does not guarantee the same improvement on another bike or identify one best pad for every rider.

Your questions

About these brake pads

Fitment, materials and performance explained.

What do the published test results show?

The published comparison plots braking power against rotor temperature. Follow the Gorilla Sintered curve to see its output in the Shimano XT RT86 test setup. The values are approximate readings from that test; results depend on the pad, rotor, brake setup and conditions.

How do I check that these pads fit my brakes?

Match the exact caliper model and existing pad shape to the compatibility table on this page. Do not rely on the brake lever name or series alone. Check the front and rear calipers separately, because some systems use different pad shapes at each end.

Which rotors can I use with this compound?

Use Sintered pads only with rotors approved for metallic or sintered pads. Do not use them with rotors marked “resin pads only”. Rotor diameter and thickness must meet your brake manufacturer’s specifications. Check rotor condition and minimum permitted thickness before fitting new pads.

Do new brake pads need bedding in?

Yes. Follow the installation guide and complete the recommended bedding-in procedure before demanding riding. Bedding in prepares the new friction material and establishes an even transfer layer on the rotor.

Can I use these pads on an e-bike?

Sintered pads can be used on compatible e-bikes when permitted by the brake and rotor manufacturers. Sintered pads generate a lot of heat, which can transfer to the caliper faster than with other compounds in our range. For high-heat applications, Gorilla Brakes recommends the Enduro Pro and Factory Racing compounds.

What is included in one pack?

Each pack contains 2 brake pads and 1 pad spring for one compatible caliper. Check the front and rear calipers separately before ordering two packs.
