The Hope Tech 4 V4 is unquestionably one of the best brakes on the market.

Entirely made in the UK from CNC billet aluminium, it provides an astonishing braking power, combined with the highest braking modulation and an incredible resistance to fading.

A strong, constant and controllable breaking force means that you, the pilot, can brake later without surprise and safely engage the steepest downhills without hesitation.

Built to perfection in the UK Hope factory, the Tech 4 V4 sets a new standard in braking performance. The CNC machined, monoblock aluminium design of both the 4-piston caliper and master-cylinder features the best lever to piston braking force ratio.

This technological prowess is made possible by Hope’s state of the art manufacturing process. First of all, Hope managed to improve both mechanical and hydraulic ratios by revising the master cylinder’s bore diameter, in addition to a lever redesign.

This leads to an increased modulation with less effort, thus lessening muscular fatigue and arm-pump.

What’s more, the master cylinder’s lever uses roller bearings to completely eliminate friction, resulting in a linear relationship between lever force and brake pressure, enhancing even more braking control.

In addition, the caliper was also redesigned with hybrid style pistons: a stainless steel outter shell for low friction, smooth movement and low maintenance, combined with a phenolic insert for controlled heat transfer under extreme loads.

Although the performance has been drastically increased, the ergonomics have been preserved with the famous tool-free adjustable levers that allow for instant bite point and reach tuning.

Last but not least, this pair of Hope brakes comes with aviation braided-hose for the very best efficiency. On top of being more robust to eventual crashes, the braided hydraulic hose doesn’t expand under hydraulic pressure. The full pressure is therefore transmitted to the calipers.

Rider’s questions

1 - 3 of 3 questions

Is it possible to run these on a L1E version and keep the brake light functionality? 1 answer


Quentin mto logo

Some customers have adapted a custom brake sensor. But the brakes themselves don't include the magnetic contractor to trigger the light signal.

Is the blue set a match for the "standard" shade of blue on warp 9 pegs or closer to the blue of smpro wheels? Will it look ok with these other products? 1 answer


Quentin mto logo

I haven't been able to compare to the W9 blue, but it's a pretty go complement with the SMPro anodised blue.

are the hoses cut to the size for a surron or do i need to cut them myself 1 answer

You need to adjust them to your desired length yourself as it will depend on many factors (stem and bars height, swingarm length…)

Quality brakes

Nice quality brakes with a lot more feeling than the stock brakes.

I recommend this product






De remmen werken perfect voor de surron met bac4000 controller. Groot verschil met de originele remmen. Ik ben er heel tevreden over.
