FAQ - What to do if the bite point on your disc brakes is spongy, soft or simply not right?

Measures against a spongy, soft or simply not right bite point.

 

CHECK THE INSTALLATION:

Has the brake caliper been mounted correctly?

Make sure that the brake caliper is sitting flat and tilt-free on its mounting and that the adapter is correctly mounted.

Align the brake caliper height:

When installed correctly, the brake pads should adequately cover the friction ring of the brake rotor – they shouldn’t contact the struts of the brake rotor. Spacers to fine-tune the height of the caliper are available via our dealership partners.

Align the brake caliper with the brake rotor:

Make sure that the brake caliper is correctly aligned with the brake rotor. The brake rotor must run centered through the brake caliper gap – it must not grind on the brake pads. Tip: Align the caliper first, adjust rubbing pads afterwards. If the caliper isn’t perfectly centered, it can impact the feel of the bite point and will make it hard to adjust the brake rub-free. You can use the gap through which the rotor runs as a point of reference. Rubbing pads can then be taken care of by mobilizing the pistons

Check the attachment of the brake rotor:

For 6-hole brake rotors, don’t fully tighten the screws fully right away, start by tightening them only for a few turns – then turn the brake rotor clockwise to center it and prevent movement during the braking process. Now tighten the screws in a star pattern to a maximum torque of 4 Nm.

 

CHECK MATCHING FRICTION SURFACES FOR WEAR:

Check the thickness of the brake rotor and the brake pad. The rotor must not be less than 1.8 mm thick. Also check the thickness of the brake pads. The combined thickness of pad and the carrier plate must not be less than 2.5 mm. You can use the MAGURA transport device to test this.

 

CHECK THE BITE POINT AND THE SYSTEM FOR LEAKS:

Check the filling level of the system and look for leaks. Bleed the system in accordance with the following instructions.

 

 

Has your brake been bled and your bite point is good, but the brake seems to be lacking power?
