Brake HOPE Tech 4 E4 | kevlar hose | black-orange

Brake HOPE Tech 4 E4 | kevlar hose | black-orange

Reference: T4E4CR

HOPE Tech 4 E4 builds on more than 25 years of experience in the design of hydraulic brake systems. The HOPE Tech 4 brake lever uses a new internal piston seal to reduce friction and the pivot now pivots on roller bearings compared to the Tech 3 version, which has reduced the stiffness of the piston spring. The lower spring stiffness therefore provides a lighter lever action, reducing rider forearm fatigue during long braking sessions. The longer end lever also provides increased power and better modulation of braking. The updated E4 caliper uses hybrid style pistons with a smooth stainless steel outer shell with phenolic liner allowing for smoother movement and less maintenance, while still being able to handle high temperatures without heat transfer during extreme use and descents.

Product Details

Brake lever

the brake lever body is made on CNC machines from 2014 T6 aluminium alloy, which is used in aerospace
ergonomic aluminium brake lever with a very soft step thanks to the roller bearings
longer lever offers a 30% increase in power over the Tech 3 version and modulation or power delivery over a longer lever step range
the end of the lever is equipped with small dimples at the end for firm contact between the gloved finger and the lever surface
thanks to the "snap-on" handlebar sleeve, the profile is reduced and there are no protruding screws
the lever can be combined with adapters for mounting the shifter directly on the brake lever sleeve with a 30° tilt
the lever is specifically left or right handed and the correct model must be purchased for its positioning
the lever can be removed from the handlebars without removing the grips or the shifter
9.5mm brake piston is sealed with 1x conical seal and 1x o-ring
precision machined and tested hydraulic axial system using DOT 5.1 brake oil
with the HOPE Tech 4 brake lever it is possible to adjust the distance of the lever from the handlebar and the lever step without the need for tools (by turning the wheels on the end lever)
expansion tank cap, available in various colour combinations (black, silver, purple, red, blue, orange)
set screws for adjusting the lever pitch and distance can be purchased in different colour combinations (black, silver, purple, red, blue, orange)

Brake caliper

the caliper, like the lever, is made on CNC machines from 2014 T6 aluminium alloy, which is used in aviation
the caliper is made from a single piece of CNC machined aluminium and there is no loss of power as with a split caliper
The HOPE E4 caliper is a 4-piston caliper, i.e. it contains a set of 4 independent pistons
The large 16mm pistons give the brake high performance in all situations
the pistons are hybrid or made of smooth stainless steel and are filled with phenolic inserts to absorb the increased heat load
the caliper is equipped with an expansion spring between the brake pads
the pads are secured in the caliper by a locking screw
the caliper is supplied with organic HOPE Race brake pads (green)
This is a compound that has increased efficiency, long life and is faster to break in
this is a version of the pads that is bonded into one via 2-pistons on each side
WARNING: the pads must be run in before use, or the bed-in process must be carried out (repeated starting and smooth braking)
swivel banjo brake hose connection, which allows the hose to be directed away from the caliper and towards the wheel
post mount or PM mounting of the brake caliper
M6 screws for mounting the caliper to the frame or fork (using an inbus wrench) are also included
precision engineered and tested hydraulic system using DOT 5.1 brake oil

Hose

the brake is supplied with a 5mm diameter kevlar hydraulic hose
the length of the unshortened hose is 2000mm
parts for shortening the hose to the required length are also included (1x hose barbed fitting / 1x hose olive / 1x copper seal)

Recomended disc rotor

combine the brake with HOPE Floating, HOPE Standard brake discs
Recommended discs are available in 140, 160, 180, 183, 185, 200, 203, 205, 220 and 225mm diameters

Weight

the weight of the whole brake is 343g including the full length of hose, without disc and fixing M6 screws)
