FAQ - What to do if your bike’s braking performance suddenly deteriorates?

If a deterioration in braking performance becomes noticeable – even if the system is tight and the bite point is good – try these measures to remedy the situation



Check the thickness of the brake pad

The combined thickness of the pad and the carrier plate must not be less than 2.5 mm. You can use the MAGURA transport device to test this (see the Manual).


Check the pad for glazing

Glazing of the brake pad leads to a harder surface. This changes braking performance and the coefficient of friction, causing vibrations and noise. Glazing has occurred when the brake pad has a smooth and shimmering surface that cannot be removed by grinding. Please replace glazed pads and ensure that the brakes are correctly run in.



Check the amount of wear on the brake disc

The thickness of the brake disc must not be less than 1.8 mm.


Clean the disc

Clean the disc thoroughly with methylated spirits or a brake cleaner.



If the insufficient braking power usually occurs at the end of descents, the brake disc diameter should also be checked and, if necessary, changed to a larger disc to give the brake better thermal stability.



Safety information:

We strongly recommend that you read the enclosed manual/operating instructions before using MAGURA products. Always observe and follow all instructions for assembly, operation and maintenance in this manual and the operating instructions of other manufacturers whose products are used on your bicycle – and please don’t overestimate the products’ abilities. Have assembly and maintenance work carried out in a specialist bicycle workshop or in an authorised MAGURA Service Centre, where a professional job is guaranteed.
