► Brake maintenance
For MTB/Racing bikes: Always make sure that the brake levers are tightly fixed, and
ensure that braking is effective after only a short squeeze of the lever. Further, it is
recommended, particularly in the case of rim brakes, that the amount of wear on the
brake pads, the alignment and tight fit be regularly checked (see previous chapter).
For disc brakes, always make sure that the lining thickness does not fall below the
minimum specified thickness, and that the lining is always parallel to the brake disc.
In the case of hydraulic disc brakes, it is important that the brake lining area of the
hydraulic brake is kept clean; otherwise the disc brakes can suffer a massive loss of
braking performance. Occasionally check the brake lines and connections for leak-
age.
► Tyres
The maintenance of wheels and tyres consists of regular checking of tyre pressure,
tyre condition (above all tears) and correct valve seating (see the previous chapter)
If your bike has rim brakes, there is the danger, under certain circumstances, that
rim faces may be worn down in time ("brake wear") and may eventually wear
through. To minimise this risk, take a closer look at your rims every now and again.
If you are unsure, seek the advice of your dealer!
Tyre pressure may be shown in a different unit on your pump pressure gauge, or
separate pressure gauge used for checking.

If you need to replace the brake linings, use only linings
intended for, and specifically labelled as being suitable for
your brake unit. Always make a series of braking tests in a
safe environment after installation of new brake linings.
