Your questions

About these brake pads

Fitment, materials and performance explained.

Is this the same compound as Enduro Pro Semi-Metallic?

No. This listing uses standard Semi-Metallic from the Gorilla Brakes Performance range, intended for commuting, road, gravel and lighter trails. Enduro Pro Semi-Metallic is a separate compound with its own published ratings and test results.

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 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.

Which compound does Gorilla Brakes recommend for e-bikes?

Gorilla Brakes positions standard Semi-Metallic in its Performance range for conventional bicycles. For e-bike riding, Gorilla Brakes recommends the Enduro Pro and Factory Racing brake pad ranges. Match the pad shape and complete brake setup to your bike and its 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.

They have not been truly put to the test just yet, but already seem to have vastly improved braking compared to the previous pads. Fitted easily and without any problems, after arriving promptly.

I haven't had a chance to fit the brakes yet, but Gorilla Brakes emails me fairly persistently asking for a review, so I can say they were delivered promptly.

I placed my order late one evening and I have to admit I was not entirely on the ball. I was surprised and very impressed to receive a call the next morning from Gorilla as they suspected I had ordered the wrong disc rotor for my calliper. The order was amended and parts arrived promptly.
I fitted the parts on my old winter bike, a Specialized Diverge I bought second hand with mechanical disc brakes which have never been good. It was getting to the stage that I was going to permanently demote it to the turbo trainer.
I have been out for a few rides and the brakes have bedded in a treat. I am so happy as it’s made an ok bike good again and I now feel safe riding it. Thanks Gorilla brakes, I will certainly be back for more parts.
