2- regulate the distance from the lever, in order to create the best feeling
3- activate the brake lever, until it touches the handlebar or half handlebar, so that the piston can make an entire spin with a fluid movement
Reservoir to master cylinder connection
1- use a cable with made of Teflon inside and covered by steel, which has to be compatible with the brake fluid in EPDM and with a diameter of 3mm, at least
2- join the reservoir exit with the master cylinder entrance, using the requested clamps, the extremities need to be joint with appropriate couples
3- use exclusively the brake fluid DOT4, with an high boiling point, from new packages and change it for every race
Note: the usage of a different fluid from the DOT4 can cause master cylinder’s damages
Breaking system bleeding
1- turn the handlebar or half handlebar, in order to have the reservoir in horizontal position
2- fill up the reservoir with brake fluid, during the bleeding process the oil level doesn’t have to go below the minimum level
3- activate more than one time the brake lever and fill the braking system partially
4- insert a transparent plastic tube to the bleed screw
5- bleed through the following steps:
– pull the brake lever entirely and hold it in that position
– unscrew the bleed screw and let some air and some oil flow out -repeat this operation until no more oil will come out of the bleed screw, and check
– that the oil level doesn’t go below the minimum level
