Take a closer look at Gorilla Brakes Factory Racing Stealth pads — designed for quiet braking, smooth modulation, and dependable braking performance.
Compatible with selected Tektro heavy-duty 4-piston e-bike, cargo-bike and trike brake calipers requiring the extra-thick 5mm Q13RS pad format.
Gorilla Brakes Factory Racing Stealth 5mm Pads combine our high-performance Factory Racing friction compound with an acoustic damping layer designed to reduce vibration and unwanted braking noise. Developed for the increased weight and braking demands of e-bikes, cargo bikes and utility cycles, they provide powerful braking, progressive control and consistent performance under load.
These pads use the 5mm Q13RS pad profile. They are thicker than standard Tektro and TRP 4-piston pads, so the brake model and front/rear caliper position must be checked carefully before ordering.

⚠️ Please note: The rear calipers fitted to the Tektro HD-M530 and HD-T532 use a different 2-piston pad. These 5mm Q13RS-format pads fit the front caliper only on those two brake systems.
Auriga Twin+ owners: This product contains enough pads for one caliper. A twin-caliper system normally requires two pairs for a complete pad replacement.
🔥 Compound Type: Factory Racing Stealth
The Factory Racing Stealth Compound is designed to deliver strong, predictable braking while minimising noise and vibration.

The folks at gorilla brakes were really helpful in discussing the best brake pad option for my bike/riding, and taking the time to explain about getting the most from the brake setup, thanks for the link to the video too, really helpful. The pads are on, and will see how they go in the Alps in a couple of weeks time.
Hi David , thank you for your kind words! We're thrilled to hear the guidance was helpful. Enjoy your ride in the Alps, and we hope the pads perform perfectly. Safe travels!

The brake pads look great. Shipping was fast. I bought these to stock up after I changed my brake pads. I can't try them out until my next
brake pad change possibly later this year I'll have a set on my bike.

Bonjour .ce coup çi j'ai bien reçu la vis par contre elle a la même mesure que la première commander et donc je l ai recoupé a34 mn . Ya peut être du recadrage a faire au niveau préparation de commande .mais vous avez été réactif au première de ma part merçi
Amicalement
Bonjour Michel, merci pour votre retour. Nous sommes désolés pour la confusion avec la mesure. Nous allons vérifier notre processus pour éviter cela à l'avenir. N'hésitez pas à nous contacter si vous avez besoin d'aide. Cordialement, l'équipe Gorilla Brakes.
Replaced sintered pads with Factory Racing ones on my SRAM G2 brakes and now all squealing stop stopped. Just a better riding experience now and of course they have good stopping power.
