Description:

Who screwed themselves, must once more the brake calipers on and take down – be it because the wheels outside there, be it because the saddles to be cleaned. Not rocket science, if you heed the most important rules.


The coupling and uncoupling of the brake calipers on the bike is a work that does not tolerate crudeness, either in the hobby shop or in the heterogeneous car-repair shop or a car tire dealer. Often they are working with compressed air impact wrench to install the wheels off and on. The brake calipers, and have to take away also, however, no impact wrench.

Stores
On motorcycles with dual disc brakes at the front wheel to the general Radausbau the calipers down. These (and for installation of course) you need a full tool:

• Torque wrench
• Allen, Allen or Torx nut for the brake caliper mounting bolt
• The key to any existing brake line mounting bolt and ABS sensor mounting
• Bungee cords / strip to the brake calipers Weghängen
• Adhesive tape to cover the rim (if one encounters the other hand, when removing the caliper will not damage the paint of the rim).

Aufbockhilfen
Jack up the machine properly prior to dismantling the brake calipers on. Even if the machine has a center stand, you need to remove and install the front wheel in addition to a hydraulic jack and wooden blocks. So that the machine is lifted the front so that the front wheel about an inch from the ground is free. on the motor housing or blocks of wood and jack carefully start another stable conditions can not crush (NOT the oil filter), exhaust pipes.

Unscrew the brake calipers

• in an ABS wheel speed sensor of the machine is attached to the fork lowers, it must be removed. If it is however on the caliper bracket, it can stay mounted in most cases.
  Warning: Carefully work around the sensor cable, bend or even move it!
• Brake calliper: Only unscrew the screws holding the brake caliper is secured to the fork. Loosen the other screw – they stick together to fix the caliper or brake line.
• Calipers move from the brake discs. weghängen with rubber bands carefully – brake hoses as little as necessary, twist and do not bend!

Brake calipers screw

• Brake discs with brake cleaner.
• Slide calipers on the discs, screw bolts and tighten slightly at first.
• Bolts with the tightening torque specified by the manufacturer. Both screws must be checked at least twice each to the correct torque.
• ABS sensor and screw it tight.
• Brake line brackets with screws.
• Press brake several times to the pads on the discs.
• Wheel through turn and check that it is free and easy: it may be to hear any grinding noises.
• Dirt, grease, oil and wipe off the assembly points!
  Important: Last control – tightened all the screws?

Rear brake caliper
With most machines you need to mount the rear caliper screw off, because that on the caliper holder
(“Brake anchor plate”) is fixed, which is done when taking off the rear axle with integral brake caliper to the side. Does the caliper
be screwed otherwise apply the same procedures as for the front wheel.

When the installation is important to note:

• When the machine for removal and replacement of the wheels on a car lift, is essential to the front and on both sides secured with straps.
• Is the machine on the floor, make sure that it is not only safe and secure, but no one pushes the other hand by mistake and therefore they either roll over or tip over from the stand side.
• If both wheels simultaneously developed, must be timely and secure with straps carefully before beginning construction of the wheel!
• If the calipers are removed, not the brake lever! In the worst case, the pistons move from the brake caliper, which is a nasty mess.

Loctite is needed?
Some mechanics swear by the installation of the brake caliper mounting bolt on a liquid thread lock such as Loctite “medium strength”, or otherwise give a drop of oil or fat to the special aluminum thread. There is no universal rule for all types of motorcycles. It is important in any case that the external threads of the screws and the internal threads in the caliper mount perfectly in order, cleaned up the screws before re-turning with a brass brush and are tightened to the specified torque.
