Dominion A4 | black-purple | limited edition

This limited edition purple HAYES Dominion A4 brakes can only be seen on HAYES sponsored riders such as Rémy Metallier, Hannes Klausner, Pat Smage, Ali Clarkson, Clemens Kaudela and Jordi Bago. The purple colour is a reference to the early days of MTB cycling, when HAYES brought to the world a technology that changed our sport forever.

You can only buy the limited edition Dominion A4 in black and purple once a year and once it sells out, you'll have to wait until next year!

Brake lever

brake lever body is made of forged aluminium alloy
Ergonomic aluminium brake lever with a very soft step thanks to the roller bearings
the end of the lever is fitted with small dimples at the end for firm contact between the gloved finger and the lever surface
the lever can be combined with adapters for attaching the gearshift directly to the brake lever sleeve
the lever can be used on the left or right side of the handlebar (flip-flop)
the lever can be removed from the handlebars without removing the grips or the shifter
precision engineered and tested hydraulic axial system using DOT 5.1 brake oil
Brake lever piston has a conical seal and a special slip ring to reduce friction
the HAYES Dominion A4 brake lever can be adjusted for the distance between the lever and the handlebars (by turning the wheel on the end lever)
with the HAYES Dominion A4 brake lever it is possible to adjust the dead lever step using a 2mm inbus key (by default the shortest possible step is set)
the HAYES Dominion lever has been designed to have the shortest possible deadstroke - i.e. the time without the onset of brake power (pad and disc contact)
the fluid reservoir is large so that there is no risk of air entering the system even with significant pad wear
Standard Reach Lever (RRL) = standard distance of lever blade from handlebars

Brake caliper

the caliper is made of cold forged aluminium
the caliper is made of two separate pieces and connected by two large screws
further increase in the strength of the caliper is provided by the locking screw of the plates called King Pin
The HAYES Dominion A4 caliper is a 4-piston caliper, i.e. it contains a set of 4 independent pistons
the large 17mm pistons give the brake high performance in all situations
the pistons are made of lightweight aluminium alloy to ensure rapid heat transfer to the caliper from where it is then transferred to the surrounding area
the pistons are fitted with a square (in cross-section) seal, which has specific elastic properties to maintain perfect retraction even at high pad run-out
the caliper is equipped with an expansion spring between the brake pads
the pads are secured in the caliper by a locking screw (HAYES King Pin)
the caliper is supplied with semi-metallic brake pads T106 (installed in the brake caliper), but also sintered pads T100
this is a version of the pads that is joined into one via 2-pistons on each side
WARNING: the pads must be run in before use, or the bed-in process (repeated running 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
detailed adjustment of the caliper and alignment to the disc is possible by means of small worms on the post mount (crosshair system)
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
Two-Stroke bleed port system allows you to bleed separately without having to pull fluid through the lever

Brake hose

brakes are supplied with Kevlar hydraulic hose HAYES K8 with inner diameter (ID) 2.5mm outer diameter (OD) 5.5mm
the length of the unshortened hose is 1800mm
parts for shortening the hose to the desired length are also included in each pack of the brake (1x hose insert / 1x hose olive)

Disc otor

supplied with HAYES D-Series brake discs
default disc width = 1.95mm
minimum disc width = 1.7mm
disc mounting on hub = 6 screws (IS)
