Match the exact caliper model and existing pad shape to the list below before ordering. These pads fit RX4+ and the listed E4 calipers. The original RX4-SR uses a different pad shape, so RX4 and RX4+ names should not be treated as interchangeable.

E-bike recommendation

Gorilla Brakes positions standard Ceramic 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.

Rotor compatibility

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.

Compound performance

Ceramic

Smooth, progressive control with a quiet braking character for everyday XC, road, gravel and commuting. Part of the Gorilla Brakes Performance range for conventional bicycles.

Actual braking performance and wear depend on your brake setup, rotor, bedding-in and riding conditions.

Heat management

Aluminium or steel backing plates?

These pads use a steel backing plate. The compound guidance describes the standard Ceramic friction material.

Fitting and bedding in

Follow the installation guide for your braking system, then complete the recommended bedding-in procedure before normal riding.

Your questions

About these brake pads

Fitment, materials and performance explained.

Is Ceramic the same compound as Enduro Ceramic?

No. This listing uses standard Ceramic, an everyday option from the Gorilla Brakes Performance range for XC, road, gravel and commuting. Enduro Ceramic is a separate compound aimed at warmer, dry rides.

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?

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.

Pads worked as stated amazing stopping power and survived a lot of steep Morzine and surrounding area runs. Will definitely be buying them again.

Hi Carl, we're thrilled to hear you enjoyed the pads and experienced great stopping power on your rides! Thanks for your support, and we look forward to your next purchase.

I purchased those pads because I was annoyed out of my mind from the notorious Hope squeek. Well.... those are squeeky too! Nothing to complain about the brake power thought!

Hi Houssam,

Thank you for the feedback, and I’m glad to hear the braking power is good.

With Hope brakes, squeal is usually caused by vibration in the braking system rather than the pad compound itself. Hope brakes are very powerful and the calipers can be quite sensitive to small setup issues, especially contamination, rotor condition, piston movement, alignment, or bedding-in.

The Factory Racing Stealth compound is designed to be quieter than a full sintered pad, but no pad can completely remove noise if the brake system is creating vibration. I would recommend checking that the rotors are fully cleaned, the caliper is perfectly centred, the pistons are moving evenly, and that the pads have been bedded in with firm repeated stops.

If the squeal continues, send us a bit more detail on your rotor type, how old the rotors are, and whether the noise is front, rear, or both, and we’ll be happy to help you narrow it down.

Kind regards,
Gorilla Brakes

Bought them to use on our e-tandem very pleased with the performance.

Hi Chris, we're thrilled to hear you're pleased with the performance of the HOPE E4 / RX4+ brake pads on your e-tandem! Thanks for sharing your experience, and happy riding!

Initially these were ok, however even this compound will squeal, hard braking is required to bed them in. Not the performance I expected.

Hi,
Thank you for your feedback, and sorry to hear the pads have not performed as expected.
If there is very little braking power, that normally points more towards a brake setup issue rather than the pad compound itself. Factory Racing Organic pads should have good initial bite once bedded in, so if you are needing to brake extremely hard just to get performance, we would recommend checking the brake system.
The most common causes are air in the brake line, a brake that needs bleeding, sticky pistons, poor pad contact on the rotor, or rotor contamination. If the lever feels soft, pulls too close to the bar, or the power feels weak even with new pads fitted, a brake bleed would be the first thing we would recommend.
Squeal can only happen if the pads and rotor are not bedding in correctly, or if the rotor has contamination or vibration through the caliper.
Please let us know what brake model you are running and whether the lever feels firm or spongy, and we can advise further.

very quiet brake and powerful stopping

Hi Mark, we're glad to hear you're satisfied with the quiet and powerful stopping performance of our brakes! Thanks for your feedback.

Significantly quieter than standard stock Hope E4 pads particularly in the wet. Could not really determine if braking was noticeably better however. Long term durability still under review.

Hi Simon, thanks for sharing your feedback! We're glad to hear the pads are quieter, especially in wet conditions. We'll be interested to hear about their long-term durability. Feel free to reach out if you have any questions or need assistance!

Stop me like a stoppy thing

Hi Bill, glad you found the brakes effective! If you have any questions or need assistance, feel free to reach out. Thanks for choosing Gorilla Brakes!

Awesome service, and great brake pads.

Thank you for your support

Finally i have brakes that work and are not just quiet, they are silent.

I thought id wasted a lot of money on the RX4s as they have not been any better than the GRX and I have had multiple mechanics try to stop the squealing with no luck. Turns out both compounds of original pads are just junk.

Customer service at GB is 10/10

Thank you for the review really appreciate you taking the time to share this.
Great to hear you’ve finally got the brakes running how they should silent and consistent. That’s exactly what a properly set up system delivers, and it’s good we could help get you there.
You’re not alone with that experience either when everything’s dialled (alignment, pistons, transfer layer), the compound can do its job properly and the noise disappears.
If you ever need anything going forward — setup advice, compound tweaks, or just a second opinion our workshop team is always here.
Enjoy the ride 👍

After bedding-in the pads, modulation is awesome, stopping power is out-standing.

Thank you for your review of our HOPE E4 / RX4+ Enduro Pro Ultimate Disc Brake Pads. We are thrilled to hear that you have experienced excellent modulation and outstanding stopping power after bedding-in the pads. We aim to provide top-quality products for our customers, and we are glad to know that you are satisfied with your purchase. Happy riding!

Repeat order super pads

So good I bought them again

Hi Gary,

Thank you for coming back to us — that’s the best feedback we can get 🙌

We’re really pleased to hear the Hope sintered pads delivered well enough that you bought them again. That compound is built for consistent power, heat control, and durability in demanding conditions, so it’s great to know they’re doing exactly what they should.

If you ever need setup advice or want to fine-tune your compound choice for different riding conditions, our workshop team is always here to help.

Ride safe

Very good and work really well

Thank you for your positive feedback!
