Hope E4 Brake Pads FAQs

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

Do these pads fit Tech 3 E4 and Tech 4 E4?

Yes. Choose the HBSP323 shape for Hope E4 calipers, including Tech 3 E4 and Tech 4 E4. Check the caliper model rather than choosing only by the lever's Tech name.

Are these the same shape as RX4+ and RX4-SH pads?

Hope E4, RX4+ and original RX4-SH (Shimano) use the HBSP323 shape with a 37 mm reference width. This collection presents dedicated E4 listings; choose the RX4 collection for RX4+ or original RX4-SH listings. Original RX4-SR uses the smaller HBSP359 shape and does not fit E4.

Which compound should I choose?

Compare the available compound ratings and riding guidance, then check the selected product's rotor compatibility and pack contents. The compound changes the riding characteristics; the HBSP323 shape determines the fit.

How should I fit and bed in the pads?

Follow Hope's instructions for your exact caliper and the installation and bedding-in guidance for your selected pads. Check the rotor condition and required pad-retention parts before fitting.
