Sinter Model 020 Hope

Hope's Tech V4 caliper is the newest four-piston design in the British brand's catalog, with a refreshed pad pocket and a larger piston area than the Tech 3 generation it sits above. The Sinter Model 020 is the organic-compound pad specifically built for the Tech V4. One pad shape; one caliper family.

What's in the kit

One caliper's worth of pads (2 pads, left and right) for the Hope Tech V4 pocket. The kit ships with the spring, pin, and bedding-in instructions. Order two kits if you're replacing front and rear pads on the same service.

Fits

Hope Tech V4 pad shape:

• Hope Tech V4 (the current four-piston generation)

The Tech V4 has a different pad geometry from the older Tech 3 E4 / M4 family; if your Hope caliper is Tech 3-era, the Model 016 is the correct Sinter fitment. The Hope RX2 takes the Model 043. The V4 is identifiable by the newer-generation caliper body shape and the larger pad-pocket aperture compared to the Tech 3 calipers it replaced.

Compound and feel

Sinter's organic ceramic-loaded compound is calibrated for the Tech V4's larger piston area and the more aggressive pad-to-rotor contact pattern it generates. The compound holds its bite at higher pad-surface temperatures than a standard organic, which matters on the V4 because the new caliper design is targeted at enduro and aggressive trail use where pad temperature climbs faster than on the Tech 3 platform. The resin matrix runs quiet on dry rotors, modulates linearly through the Tech 4 lever's progressive feel, and bites cleanly from the first pull.

Sinter's Ljubljana metallurgy, Unior's Zreče forge

Both brands trace back to Slovenian manufacturing: Sinter has been making friction materials in Ljubljana since 1969, and developed the first disc brake pads in the former Yugoslavia in 1972. Unior has been forging hand tools in Zreče since 1919, and is the official technical partner of multiple World Tour and downhill teams. Euro Toolworks distributes both brands in North America. The Hope Tech V4 is Hope's first new four-piston design in over a decade, and the Model 020 is the pad that fits it.

Pro tip from our mechanics

The Tech V4's larger piston area means a longer pad-bedding window than the Tech 3 calipers most Hope owners are used to. Sinter's bedding instructions cover the standard sequence; on the V4 specifically, expect an extra five or six bedding cycles before the pad seats fully against the rotor. The first ride feels under-bedded; by the third or fourth ride, the brake settles into the bite-and-modulate pattern that's the V4's design intent.

FAQ

Which brakes does the Sinter Model 020 pad fit? This is the Model 020 shape, made for the Hope calipers that take this particular pad. Hope has produced several caliper generations with different pad shapes, so the safest move is to remove a worn pad and match the backing plate, mounting tab, and pin hole against this one rather than going by name. A model number stamped on the old pad makes confirmation easier still. If you are unsure which shape your Hope caliper uses, send a clear photo of the old pad and we'll confirm it.

Are these sintered or organic pads? They're organic. Despite the brand name, Sinter only makes organic brake pads, not sintered-metal. Organic compounds run cooler at the caliper, give you more lever feedback and modulation, stay quieter, and put less wear and vibration into your rotors than a sintered pad.

Do I need to reset the caliper pistons before fitting new pads? Yes. As your old pads wore down, the pistons advanced to keep contact with the rotor, so there won't be enough room for the thicker new pads. Push the pistons back into the caliper before you install the new set. A plastic tire lever or a dedicated piston-reset tool works; press evenly so you don't cock a piston in its bore, and keep brake fluid clean off the pad faces.

How do I bed in the new pads? Bed them in before your first real ride. Get up to a moderate speed on flat ground and drag each brake firmly to slow down without locking the wheel, then repeat ten to twenty times until the lever feels consistent. This transfers an even layer of pad material onto the rotor and brings the pads up to full bite. Avoid hard, locked stops until they're bedded, since that can glaze the surface.
