Good quality and only place I could find pack of 4 rather than them.coming in 2's at double the price 😆
Great so far! Stop exceptional and low noise.

Suitable for compatible e-bike brakes
Enduro Pro Ultimate is an e-bike-rated compound. Use this pad shape only with the compatible calipers listed here, and match the complete brake setup to your bike and total load.
Rotor compatibility
This compound is suitable for all bicycle disc brake rotor types, including rotors marked “resin pads only”.
Rotor diameter and thickness must still meet your brake manufacturer’s specifications. Check the rotor’s condition and minimum permitted thickness before fitting new pads.
Compound performance
Enduro Pro Ultimate
Our published compound testing shows strong braking output as rotor temperatures rise. Enduro Pro Ultimate also achieved the best wear resistance within the bench test group.
These findings describe the samples and setups tested. Actual performance and wear depend on your braking system and riding conditions.

Caliper temperature vs rotor temperature

All curves shown
About this test
The horizontal axis shows rotor temperature; the vertical axis shows caliper temperature. At the same rotor temperature, a lower curve means a cooler caliper in this test setup. Consider this alongside braking power, pad life and correct fitment when choosing pads for long descents or heavier loads.
Indicative test comparison. Results relate to the tested samples and setup.
Compare braking power across compounds
All eight curves use the Shimano XT RT86 rotor. Choose a compound to highlight its tested result.
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.

All curves shown
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.
Two Enduro Pro Ultimate results are shown: the main comparison sample and the aluminium-backed sample. Both used the Shimano XT RT86 rotor. Compare each curve as its labelled backing-plate configuration.
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.Fitting and bedding in
Follow our installation guide, then complete the recommended bedding-in procedure to prepare the new friction material and establish an even transfer layer on the rotor.

Your questions
About these brake pads
Fitment, materials and performance explained.
Do these pads fit both brakes on Orion HD-M735 or Gemini HD-M530?
No. On Orion HD-M735 and Gemini HD-M530, these pads fit the rear two-piston caliper only. The front caliper uses a different four-piston pad shape. Dorado HD-E720 and HD-E725 are also four-piston applications and do not use this pad shape.
Are these pads 4 mm or 5 mm thick?
The supplied Enduro Pro Ultimate pads are 4 mm thick. Gorilla Brakes confirms their use in the listed P21.11 / E11.11 applications originally specified with 5 mm pads: HD-M530 rear, HD-M390, HD-T390, HD-E395, HD-E540, HD-T540, HD-E545 and HD-T545. This is a compatibility statement for those listed applications, not a claim that the supplied pads are 5 mm thick.
How many brakes does one pack cover?
Each pack contains 2 steel-backed brake pads, supplied at 4 mm thickness, and 1 pad spring for one compatible caliper. On Orion HD-M735 and Gemini HD-M530, this pack fits the rear two-piston caliper only; the front needs the different four-piston pad shape.
Are the ratings for this pad shape or for the compound?
The ratings describe the Enduro Pro Ultimate friction compound, not this caliper, backing plate or complete braking system. Braking performance also depends on the brake setup, rider and load, terrain, conditions and bedding-in.
Can these pads be used on an e-bike?
Enduro Pro Ultimate is an e-bike-rated compound. Use this pad shape only with the compatible calipers listed here, and match the complete brake setup to your bike and total load.
Do the pads need bedding in?
Yes. Follow the installation and bedding-in guides before normal riding. Bedding in prepares the new friction material and rotor contact surface.
Does the quietness rating mean the pads are silent?
No. The compound has a quietness rating of 8 out of 10. Noise can still vary with the rotor, conditions, alignment, contamination and bedding-in.
