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

Compound performance

Factory Racing STEALTH

Quiet braking and control for trail, road and gravel. Its tested profile covers dry and wet braking, lifespan, quietness and heat dissipation.

Factory Racing STEALTH appears as Factory Racing Stealth Purple in the comparison data. Scores are approximate readings from the supplied chart; actual braking and wear depend on your brake setup and riding conditions.

Compound ratings out of 10

These scores describe the friction compound.

Dry braking: ≈9
Wet braking: ≈8
Lifespan: ≈8
Quietness: ≈8.5
Heat dissipation: ≈9

Approximate ratings out of 10 from the supplied Factory Racing compound chart. Higher ratings indicate stronger performance in that category; a higher quietness rating means quieter braking.

Compound testing

Factory Racing STEALTH: braking power

These pads use a steel backing plate. The ratings shown on this page describe the Factory Racing STEALTH friction compound.

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 Factory Racing Stealth Purple curve for the STEALTH compound. In the Shimano XT RT86 rotor comparison, its highest plotted output was approximately 1,030 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 performance ratings describe?

These approximate ratings describe the Factory Racing STEALTH friction compound and are read from the supplied Factory Racing chart. Individual pad shapes, backing plates and calipers have not been separately scored. Higher ratings indicate stronger performance in that category; a higher quietness rating means quieter braking.

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?

This compound is suitable for all bicycle disc brake rotor types, including rotors marked “resin pads only”. Rotor diameter and thickness must meet your brake manufacturer’s specifications. Check the rotor’s 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?

Yes. Factory Racing STEALTH 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.

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.

Early days for these which is why it’s 4 and not 5 stars. The fit is great and they have been quiet and strong so far. Just need to see how they last to go to 5 stars

I used gorilla pads in my road bike and found them easy to bed in and they have given me good braking all winter. It was an obvious choice to order gorilla pads for my Mtb. After the post office lost them gorillas customer service was top notch, the second set arrived with the first the next day. Gorilla supply good pads with perfect service and I can’t see me using anyone else now.

Hi there! We're so glad to hear that you've had a positive experience with our Gorilla Brakes pads for your road bike. We take pride in providing easy-to-bed-in and reliable braking performance, even in winter conditions. Thank you for choosing us for your MTB as well. We apologize for any inconvenience caused by the lost package, but we're happy to hear that our customer service team was able to promptly resolve the issue. We appreciate your support and look forward to being your go-to for brake pads in the future. Ride on!

Both sets of SRAM G2 brake pads I bought failed before the pads wore out. The pad detached from the backing after about 10 short rides.

Thanks for your feedback — we’re sorry to hear about this experience.
Pad material separating from the backing plate is extremely uncommon, so we’d really like to investigate what may have happened here.

Please contact our support team with a couple of photos of the pads and your brake setup and we’ll be happy to look into it and help resolve this for you.

I spoke to Gorilla as I wasn’t sure which compound to use for the application I needed pads for, they was very helpful and recommended the Semi metallic. The pad works perfect mated to the Hope floating discs.

Thank you for sharing your experience. We are really please to hear that our customer service team was able to assist you in finding the right compound for your needs. We take pride in providing excellent service to our customers

I don't normally do reviews, but these pads are so far ahead of the clarks and uberbikes pads I'd been using it would be rude not to shout about them. Predictable both in the dry and in the grimy freezing cold of winter. Consistent throughout their lifespan, and practically silent unless you're out in a soaking downpour, at which point the polite chirp they make when you first touch the discs is the least of your worries.
