LEWIS SP Series Specialized Sintered Metallic Brake Pads for LEWIS Calipers

LEWIS SP pads put one specialized sintered metallic compound across two-piston and four-piston LEWIS calipers, so a rider with different LEWIS brakes can stay on one compound. Two options cover the four codes, and each code serves its own caliper group.

Reading the SP30/37/40 and SP44 options

SP44 is the simple one: the SP-44-4.0 pad has a 44mm section width and is for four-piston LEWIS AX and EB calipers. SP30/37/40 groups three codes under one option, so give your caliper model and ask which of those three pads is supplied before ordering, because each suits its own caliper group.

Matching SP codes to LEWIS caliper names

SP-30 at 30mm is for two-piston calipers on LEWIS LVS2 and R2. SP-37 at 36.9mm is for four-piston calipers on LH4, LV4 and S4, while SP-40 at 40mm is for four-piston LHT and U4. Names decide the fit on SP pads, so read the model off your brake rather than guessing from its piston count.

Deciding whether sintered metallic suits your riding

Picture repeated long stops on a four-piston LEWIS AX or LH4. As a general guide, sintered metallic compounds are chosen for that kind of heat and for rough conditions, though they can run louder than softer ones, so a rider chasing quiet running may prefer another LEWIS compound.

• LEWIS AX or EB four-piston caliper: the SP44 option.
• LEWIS LVS2 or R2: SP-30, the 30mm pad.
• LEWIS LH4, LV4 or S4: SP-37, the 36.9mm pad.
• LEWIS LHT or U4: SP-40, the 40mm pad.
• Brake not named above: compare the old pad shape before ordering any SP code.

Start from the model name on your LEWIS caliper, map it to an SP code, and then choose the option that carries that specialized sintered metallic pad.
