Hope Tech EVO TR4 4-Piston hydraulic disc brakes, front and rear, with 6-bolt floating rotors

A complete Hope Tech EVO TR4 brake set for trail and all-mountain riding: two fully bled Hope brakes - front with the right-hand lever, rear with the left-hand lever - plus a pair of Hope Floating Disc 6-bolt rotors (1.8 mm two-piece floating rotor, 410 stainless outer on a CNC alloy centre). Made in Barnoldswick, UK, and fitted by Tune Cycles.

Kit includes

Front: Tech EVO TR4 front brake, right-hand lever, 2 m black hose, cut to length at fitting, racing-compound pads, fully bled
Rear: Tech EVO TR4 rear brake, left-hand lever, 2 m black hose, cut to length at fitting, racing-compound pads, fully bled
2 x Hope Floating Disc 6-bolt rotor, 180 mm, black

Options

Brake colour: choose it on the front and rear rows - the first colour is the lever and caliper body, the second the accents; pick the same on both. Rotor sizes: Hope Floating Disc 6-bolt 160, 180, 203 mm (black centre; other colours on the rotor listings). The kit defaults to two 180 mm; set that row to 0 and pick another size, or mix sizes. Hope's trail brake - 180 mm front and rear is the usual trail spec. Rotor thickness the caliper takes: 1.8 to 2.3 mm (Floating, Fixed).

Fit-up parts, sold separately (linked here and shown with this kit): Hope brake mounts, black or silver for a rotor bigger than your fork or frame's native size (Hope's letter chart is on each listing), spare pads (racing compound V4 / GR4 / TR4, sintered V4 / GR4 / TR4, e-bike compound V4 / GR4 / TR4), and the Hope Easy Bleed Kit. Fluid: DOT 5.1 (DOT 4 compatible).

This kit is the 6-bolt version; the Centre Lock version is listed separately.

Already have rotors? Untick them and the price follows the parts you keep. Every part in this kit can be deselected, so a bike that only needs one end, or already has the right rotors, is not charged for the rest.

Fitting notes

Australian convention: the right-hand lever works the front brake and the left-hand lever the rear; the brakes are built that way. Hope ships every brake with a long hose, fully bled - most bikes need the hose shortened and the brake bled again, which is a workshop job (or the Easy Bleed Kit and Hope's instructions). Post-mount forks and frames take a rotor of their native size directly; a bigger rotor needs the matching Hope mount, and an IS mount always needs one. 6-bolt rotors bolt straight to a 6-bolt hub (6 x M5, 5-6 N.m). The TR4 is the successor to the Tech 4 E4 and shares the GR4's pad.

Tune Cycles supplies, fits and bleeds these brakes. Choose your options above; if you are unsure what your fork, frame or hubs take, ask us before you order.

Every part in this kit is covered by Hope Technology's warranty: disc brake systems for two years from the date of purchase against defects in materials and workmanship (proof of purchase required), rotors against defects in materials and workmanship. Brake pads and rotors are wear items; wear from normal use, incorrect installation, crash damage or modification is not covered. For any warranty claim or support, return the part to Tune Cycles and we will handle it with Hope's Australian distributor.
