Adjust your V Brakes

This quick guide is intended to help you set up and adjust the V-brakes on your bike.

Required tool:
Allen key 5mm and Phillips screwdriver (medium size) Allen key 5mm and Phillips screwdriver (medium size)

First step – check wear on brake pads

Brake shoes have a wear mark. These can differ visually.
If the wear reaches this mark, the brake pads must be replaced.
If in doubt, we advise replacing the brake shoes sooner rather than later.

Second step – check wear on the brake shoes

As a rule, bicycle rims have wear marks on the braking surface.
As soon as one of the two marks (right and left side of the rim) is no longer consistently visible, the rim must be replaced.
If in doubt, we advise replacing the rim sooner rather than later.

Third step – check the position of the brake shoes

Make sure that the position of the brake shoes corresponds to the illustration on the left with the green tick. The correct position of all brake shoes is essential for perfect and reliable braking.
The correct position of the brake shoes also ensures less wear on the brake shoes and the rims.
If you need to correct the position of a brake shoe, please proceed as follows.
– Unhook the tab for the cable attachment (9).
– Loosen the clamping screw for the brake shoe (6).
– Press the brake arm (4) against the rim (8) until the brake shoe (5) touches the rim (8).
– Align the brake shoe (5) according to the illustration above.
– Retighten the clamping screw for the brake shoe (6).

Fourth step – check the traction and pressure point

Squeeze your brake lever until you reach the pressure point. The position of the brake lever should look like the one shown on the left.
If the lever can be pulled too far or even touches the handle, the pressure point must be readjusted.
To adjust the pressure point, please proceed as follows:Try readjusting the pressure point with the cable adjustment screw. If the pressure point can be adjusted in this way, you must fix the position of the cable adjustment screw with the lock nut.
If this is not enough, follow the next steps.– Screw in the cable adjustment screw all the way in.
– Unhook the tab (9) on the cable guide (10).
– Loosen the cable clamp screw (2) until the brake cable (3) can move freely.
– Press both brake arms (4) onto the rim (8).
– Retighten the brake cable (3). Note the distances between the brake shoes (5) and the rim (8) as shown above.
– Tighten the cable clamp screw.
– Hook the tab (9) into the cable guide (10).
– Test the pressure point and, if necessary, adjust it with the cable adjustment screw.

Fifth step – check the brake arm position and adjust if necessary

Make sure that the brake arms are aligned symmetrically when the brake lever is not pulled (see fig. left, above). If this is not the case with your brake, please proceed as follows to correct the brake arm position.
– If the brake arms are set to the right (see figure above right), the return spring tension must be increased on this side and decreased on the opposite side.
– To do this, turn the left adjustment screw for the spring tension (7) by half a turn.
– Then release the right adjusting screw (7) by half a turn.
– Squeeze and release the brake lever several times.
– Then check the alignment of the brake arms.
– Repeat this process until the brake arms line up symmetrically.
