LEWIS EP-44-4.0 Sintered Metallic Brake Pads for EB and AX Calipers

If you ride an e-bike with a large four-piston caliper such as a LEWIS EB or AX, the EP-44-4.0 gives you a sintered metallic replacement made for improved heat dissipation and extended lifespan. It is worth a look when long descents keep those big calipers working hard.

Long e-bike descents and a sintered compound

A long descent on an e-bike can keep the pads working for minutes at a time, and in general that is where sintered metallic compounds are chosen. Softer pads tend to suit quieter, lower-speed riding, so think about which of those describes most of your time on the EB or AX brake.

Is your caliper a large four-piston design?

Counting pistons is not enough on its own, because four-piston calipers come in many sizes and pad outlines. LEWIS EB and AX are the named examples, so if you run another caliper, put your worn pad next to the EP-44-4.0 and compare outline and pin hole before fitting it.

Getting a fresh sintered set bedded in

Sintered pads usually need a proper bed-in before they reach full bite, so plan a few minutes of repeated moderate stops on flat, quiet ground. An even first transfer layer gives the EP-44-4.0 the fairest start before you take it onto a long descent.

• EP-44-4.0 is the full code to match when you reorder
• The compound is sintered metallic
• Suits large-sized four-piston calipers such as LEWIS EB and AX
• Piston count alone does not establish fit
• Designed for e-bike use
• Keep oil and bleed fluid off the friction surface while fitting

After bedding in, recheck that the wheel spins without a persistent rub and that the lever feels firm. If the bite still feels weak on your EB or AX caliper, look for contamination on the rotor before suspecting the pads.
