Hope’s been making some of the best MTB disc brakes in Lancashire for over 25 years now, with its basic lever shape remaining pretty similar for quite some time now. This all-new Tech 4 is something of a radical departure though, and alongside smaller improvements inside the caliper, represents a totally new brake for the brand. The biggest visible change is that the updated lever is considerably longer, bringing a claimed 30% pressure increase compared with the Tech 3. The new blade also pivots around a roller bearing closer into the bars, which, together with all-new, friction-reducing seals allows the spring rate to be reduced. This improves the mechanical advantage while braking – there’s a much lighter lever action now that’s immediately noticeable. There’s also a new hinged clamp that’s more low profile to save weight and play nicely with shifters and dropper remotes. All the tool-free bite point and reach adjustments of the Tech 3 remain, so it’s still easy to get the lever angle and reach dialled in. It wouldn’t be a Hope brake either if there weren’t some blingy anodized hues available – choose from six colour accents on top of either a black or silver lever. At the disc end, I chose the E4 caliper CNC’d from a solid piece of aluminium and using four pistons that are now redesigned as hybrid-style, blending stainless steel with phenolic inserts (a kind of heat-treated plastic). Hope says these new pistons move more smoothly and require less maintenance. One of the other big changes inside the caliper are brand new pads, with the E4s now supplied with a special ‘racing compound’ that should work with minimal bedding in and fade less than the ‘all-conditions’ organic pads also included as spares. A little birdy told me the new pads are made by the same supplier as super high-end German brakes Trickstuff, whose pads Elite DH racers frequently swap into rival brand’s brakes for ultimate performance. With the Tech 4’s installed, it’s easy to fiddle with the lever position on the fly to get it perfect as it doesn’t require an allen key. Because the corners are more angular, the lever blade still feels slightly sharper than rival brands, and the holes drilled into the blade (presumably for extra grip) can dig into fingertips a little, especially if you ride gloveless. This used to bother me, but the new lever makes it much less of an issue as you don’t need to squeeze them anywhere near as hard thanks to the lighter action. At the caliper end, you still need to be really anal about centralising the rotors during installation to ensure top performance – if the discs aren’t bang in the middle, Hope’s brakes are less tolerant than some rival brands. Set up right though, stopping power with the new lever and pads is leagues ahead of the old Tech 3s. I always felt under-gunned with the old brakes, and sore hands are etched in my memory from pulling so … Continue reading Hope Tech 4 E4 brakes review
