Spongy bite point, fading, vibrations, noise? Here are some tips on how to get maximum performance from your MAGURA disc brakes. Regularly check the installation and maintenance of your parts to ensure that your brakes perform consistently. If you want a little more, simple setup optimisations can give you additional performance. The following tips will help you get the best out of it!
Is your brake calliper correctly aligned in all directions, does the rotor run straight, and is your wheel free of bearing play?
The brake calliper itself – i.e. independently of the brake pads – must be centred as precisely as possible parallel over the brake disc rotor. Push the brake pads all the way back and check the alignment. The slots through which the brake disc runs can serve as a guide. Readjust manually if necessary.
Check your rotors and pads for wear and contamination. Dirty or glazed components can impair performance and cause noisy vibrations.
New brake pads and rotors need bed-in time to achieve their final braking power. Prevent early damage to the friction surfaces by applying your brake 20 times at 20-25 km/h on a flat road almost to a standstill. Repeat the
process until no further improvement in braking force is noticeable. Bed-in
each brake (front and rear wheel) separately. Your brakes will then be bedded
in and offer optimum braking performance.
If neglected, the end results can result in glazing, failure to reach full friction strength and accelerated wear. To keep your brake in top condition, repeat the bed-in process at regular intervals depending on the type of route.
Check your system for correct filling level, seal and bite point.
Check whether the pistons of your brake calliper extend evenly and whether you were able to centre the calliper over the disc. If the pistons extend unevenly, this can lead to vibrations in the system or the caliper cannot be centred without grinding.
It’s a brake system component that is often underestimated. By choosing the ideal pad, you can increase the braking strength by more than 20% or minimize noise. Choose a brake pad to suit your riding style.
Assuming the same manual force, a rotor with a diameter of 203 mm generates about 10% more braking force than one with a diameter of 180 mm, and a rotor´s force increase by 20%. By selecting the right diameter you can reduce the demand on arm strength, prevent brake fading and gain added safety. Heavier riders benefit especially from larger rotor diameters. Remember that larger rotors need longer pad bed-in times.
A larger rotor means greater braking force due to its larger lever. However, this is only true if you also take the rider’s weight into consideration. If a rider weighs less than 70 kg, large rotors will make it difficult to create sufficient temperature to develop the greatest braking force. Only when the rotor and the pad are at the right temperature can they achieve the best possible friction values. A larger rotor is more heat resistant, which also helps prevent fading, i.e., a drop in friction between the pad and the rotor.
Vibrations from deep-treaded tyres and oscillating bike components can generate irritating noise, especially in E-MTBs. MAGURA’s MDR-P and MDR-C rotors have special stiffening elements that block resonations. Their larger mass increases the heat window preventing and brake fading. Choose the correct rotor for your range of application.
For better performance, check other components of your bike besides the brake. Tyres, running wheels, frame and brake components can together generate vibrations and impair performance. Unfavourable configurations may make rubbing or other noises unavoidable. In extreme cases we therefore recommend testing different combinations of brake system (brake pad and brake disc), tyre pressure and tyre model.
