Hydraulic rim brakes

Bedding in disc brakes New disc brake pads and brake discs have to be bedded in carefully before you ride the bike for the first time. This process optimises brake performance. The bedding-in process involves sharp braking. You should be famili- ar with braking power and the use of disc brakes. Sharp braking without being familiar with brake performance and the operation of disc brakes, can lead to acci- dents causing severe or fatal injury. If you are unsure, you should have a qualified bi- cycle/pedelec mechanic perform the bed- ding-in process for you. Proceed as follows: To bed in the brakes, accelerate the pedelec to 30 km/h and then bring the pedelec to a halt by applying maximum braking. Repeat this proce- dure approx. 20 times. For optimal results, the wheels should not be allowed to lock.

Vapour bubble formation on disc brakes

Avoid permanently braking for long periods, as can be the case during long, steep descents. Otherwise, bubbles may form and a total failure of the braking system may occur. Severe falls and injuries may result. The brake lever may not be applied if the pedelec is on its side or up- side down. Otherwise air bubbles can enter the hydraulic system which could cause the brakes to fail. After transporting the pedelec, check if the pressure point of the brakes seems softer than before. Then slowly apply the brake a few times. By doing this, air can be discharged from the brake system. If the pressure point remains soft, please do not use your pedelec The specialist/Fischer customer service techni- cian must bleed the brake. You can avoid this problem by ap- plying the brake lever before trans- porting your pedelec and then fixing it in this position using a strap. This prevents air from entering into the hydraulic system.

Hydraulic rim brake: • If your system features a brake quick release, remove the brake unit according to the instruc- tions supplied by your manufacturer. • If you do not have a brake quick release, defla- te all of the air out of the tyre. Disc brakes with hydraulic or mechanical operation

Please do not touch the brake disc while it is rotating or directly after braking. Otherwise injuries or burns

Disk brakes: • The wheel can be removed without any further preparation. • Please note: when fitting the wheel, the disk must be slotted between the brake linings of the brake calliper and ultimately be centred without contact.

may result.

When you come to cleaning the bra- king system, please first read the instructions provided by the compo-

nent manufacturer.
