Brake HOPE Tech 4 EVO Trial Zone, black-blue

The HOPE Tech 4 EVO Trial Zone brake is the successor to the Tech 4 Trial Zone brake. The HOPE Tech 4 EVO brake lever uses 2 piston seals and 2 sliding rings to stabilize the piston. This reduces friction and allows the piston inside the lever to move more precisely. The HOPE Tech 4 EVO lever blade is mounted on bearings, which reduces wobble and friction. The smooth operation of the HOPE EVO end lever reduces the load on the forearm when squeezing the lever. The HOPE Tech 4 EVO lever offers the option of installing three versions of end levers - STANDARD, CONTROL, POWER, each with different power delivery and overall force options. The HOPE Trial Zone brake caliper is a 2-piston caliper with large 25mm aluminum pistons. This brake is designed exclusively for trials or street trials.

Please note that this brake is designed specifically for trials or street-trial use. Use on other types of bikes or sport disciplines is not recommended due to the very high and rapid onset of braking power compared to other HOPE Tech 4 EVO models! This HOPE brake has specifically reduced power modulation due to the modified inner diameter of the caliper pistons! This makes it impossible to use the brake on other types of bikes as injury could occur!

Brake lever HOPE Tech 4 EVO

• the brake lever body is manufactured on CNC machines from 2014 T6 aluminum alloy
• ergonomic aluminum end lever with super-smooth lever action thanks to roller bearings
• the end lever is equipped with small dimples at its end for firm contact between the finger and the surface of the lever under any conditions.
• the end lever have increased hook at its end to keep the finger in place even under extreme pressure
• thanks to the "snap-on" handlebar clamp, its profile is reduced and it does not contain any protruding screws
• the lever can be combined with adapters for mounting SRAM or SHIMANO shifters, or for controlling a dropper post directly on the brake lever clamp with a tilt range of 30°.
• the lever is specifically left or right, and you need to purchase the correct model for its placement
• the lever can be removed from the handlebars without removing the grips or shifters
• precisely engineered and tested hydraulic axial system using DOT 5.1 brake fluid
• the HOPE Tech 4 EVO brake lever allows you to adjust the distance of the lever (REACH) from the handlebars and the lever stroke (BPC) without the need for tools (using adjustment screws on the end lever)
• expansion tank lid is available in various color combinations
• adjustment screws for setting the BPC and REACH of the lever are available in various color combinations

A new cam designed to decrease the free lever stroke while maintaining the feel and modulation in the braking zone — a key feature of the Tech 4 brakes. The result is a slightly firmer feel at the bite point, followed by a gentle rise in power through the braking zone, further enhancing brake modulation.

The brake bleeding process has been simplified and is much cleaner than previous HOPE lever models, which will please every mechanic. The HOPE Tech 4 EVO brake lever has a bleed screw that allows you to connect the bleed funnel without having to remove the expansion tank cap.

The 9.5 mm piston of the HOPE Tech 4 EVO brake lever is sealed with one conical seal and one O-ring. The piston is now equipped with two slide rings, which stabilize the piston in the lever chamber against wobbling, thereby reducing friction and allowing the piston to move more precisely inside the lever. As a result, the lever moves very smoothly and does not strain the forearm with unnecessary resistance from the end lever.

As with all other HOPE components and brakes, individual parts for the HOPE Tech 4 EVO brake lever can be ordered as separate replacements – down to the last screw. For more information, see the ATTACHMENTS tab, where you can download a exploded view of the HOPE Tech 4 EVO brake lever and use the product codes to find the necessary replacement part, which you can purchase from us. If you are unsure, simply contact us at info@mtbrzdy.cz.

With the HOPE Tech 4 EVO brake lever, it is now possible to replace the end lever with a different variant. The HOPE Tech 4 EVO lever is normally supplied with a STANDARD end lever, which is the most suitable type for most riders, hands, riding styles, and power delivery. However, this model can be replaced with, for example, the longer POWER variant or, conversely, the shorter CONTROL model. These levers can be purchased separately, and their differences are listed below.

Brake caliper HOPE Trial Zone

• like the lever, the HOPE Trial Zone brake caliper is manufactured on CNC machines from 2014 T6 aluminum alloy
• the HOPE Trial Zone brake caliper is made from a single piece of CNC-machined aluminum, eliminating the loss of performance associated with split calipers
• the brake caliper pistons are made of aluminum alloy to be as light as possible, yet strong
• the plates are secured in the caliper by small magnets located in the center of the pistons
• the brake pads are secured in the caliper with a locking screw
• the pads have a large friction surface and are high to ensure maximum and immediate braking performance
• swivel banjo brake hose connection, which allows the hose to be directed away from or toward the wheel from the caliper
• post mount or PM brake caliper mounting
• precisely engineered and tested hydraulic system using DOT 5.1 brake fluid

The HOPE Trial Zone brake caliper is a 2-piston caliper, i.e. it contains a set of 2 independent pistons. The HOPE Trial Zone brake caliper is equipped with two large 25 mm pistons, which together provide the brake with high braking performance in all situations. The pistons are made of a lightweight but strong aluminum alloy and are fitted with small magnets that hold the brake pads in the caliper without the need for a spacer spring.

As with all other HOPE components and brakes, individual parts for the HOPE Trial Zone brake caliper can be ordered as separate replacements – down to the last screw.

Important information

• Read the following warnings carefully!
• Failure to follow these warnings may result in injury or death!
• Failure to follow the warnings below may void your warranty!

WARNING!

The HOPE Trial Zone caliper is not compatible with HOPE Floating, HOPE Floating Vented, or HOPE Fixed brake discs!
Only combine this caliper with HOPE Trial discs (default width 1.8 mm)!
The minimum thickness (disc wear limit) is 1.5 mm. Do not exceed the minimum disc thickness!

WARNING!

For proper installation of the brake, carefully read the manual supplied with each brake!
Observe the specified maximum tightening torques for all HOPE Tech 4 EVO Trial Zone brake components!

WARNING!

Use DOT 5.1 brake fluid (or DOT 4) as the brake medium.
Never use mineral oil, as it will damage the seals and the brake will have to be completely cleaned and resealed!

WARNING!

To ensure proper brake performance, it is always necessary to perform the so-called bed-in process, i.e., the process of pre-seating the pads and discs.

The process is as follows. Accelerate the bike to approx. 20 km/h and then brake to a speed of approx. 5 km/h. Repeat the process at least 20 times (a maximum of 30 times is sufficient) for each brake (front and rear) separately! After this process, the pads should be bedded-in (slightly worn), the disc should be slightly worn (sanded), and the brake should have optimal braking performance, which will increase slightly over time with each meter braked (not traveled). This process will ensure high-quality and proper brake performance.

WARNING!

Sintered / metallic brake pads with bedding-in up to 2x as long as organic pads! With sintered pads, pay extra attention to the bed-in process before using the pads, which is much more important with this type of pad.
