Brake Pads for HOPE E4 / RX4 Disc Brakes FAQs

A little help with fitment, compounds and getting ready to ride.

Do these pads fit both the original RX4 and RX4+?

Yes. Gorilla Brakes has physically confirmed every brake-pad product in this Hope E4 collection for Hope E4, the original RX4 and RX4+. This is a confirmation for these Gorilla Brakes products, not a statement that all Hope pad families are interchangeable.

Do they fit both Tech 3 E4 and Tech 4 E4?

Yes. The confirmed fitment includes Tech 3 E4, Tech 4 E4 and previous Hope E4 4-piston variants. Check the E4 marking on your caliper; choosing by the lever's Tech name alone is not enough.

Which compound should I choose for an e-MTB with E4 brakes?

Our guide recommends Enduro Pro Ultimate Orange and Enduro Pro Semi Metallic Blue for demanding e-bike use and long descents. Select the E4 / RX4 product and check that the complete brake setup is appropriate for your bike and total load.

Can I use these pads on a road or gravel bike with RX4 brakes?

Yes. Both RX4 generations are included in our physical fitment confirmation. Choose the compound for your riding conditions. For an electric road or gravel bike, use the guide's e-bike recommendations rather than choosing only by riding style.

How should I install and bed in the replacement pads?

Follow Hope's instructions for your exact caliper and our installation and bedding-in guides. Check the required tools and pad-retention parts before starting. Inspect the rotor and confirm its compatibility with the selected compound before bedding in the new pads.
