Magura HS-33 2005 brake lever tuning

Compared to HS-33 '04 you can not adjust the brake lever far enough away from the handlebar. This may be OK for small hands but not enough for people with long fingers. Possibly not all '05 levers do have this problem, so try your lever BEFORE you start the tuning.

Another problem is that the red adjusting wheel can get difficult to operate after some time.

This is how you can solve both problems:

Remove bolt using 5mm allen key.

Hold the black piston with one finger so it can't jump out (there is no internal part that is holding the piston).

Secure the piston with any thin something (like screwdriver) and some tape. Now we can start working on the acctual black lever.

Turn back the small Set-screw near the pivot drilling, about 2mm. Then fix the lever in a vice. Using a file remove some material, about 1,5mm.

Like this you will be able to adjust the lever further away from the handlebar which is good for big hands.

When the adjusting wheel is getting difficult to operate then disassamble the lever as shown above and turn the wheel until the threaded rod with ball falls out.

Apply some grease to the thread and reassamble the lever.

When the brake pads become worn out a few Millimeters then the pistons in initial position (when brake is NOT used) will point out too far (see picture).

If one piston operates more difficult then the brake pad on the other side will always rub on the rim!

To solve this problem you must place the Cylinders (silver parts) closer to the rim.

Now in this new initial position (when brake is NOT used) the brake pads will never rub the rim.

Tools: 4mm allen key.
