Adjusting the disc brake

• Apply the brake lever to check whether both sides of the disc brake brake equally.
  
• Try pushing the trailer with the brake applied.
  
  • The trailer can be pushed forward: both brakes must be adjusted more tightly.
    
  • The trailer veers to one side: the opposite side must be adjusted more tightly.
    
  • Both wheels block simultaneously and completely: the brake is correctly adjusted.

1. Brake cable knurled screw on the brake caliper
   Turn the black knurled screw on the brake caliper out to increase the brake force.
   
   
2. Y-distributor
   Turn the knurled screw on the Y-distributor out to increase the brake force.
   
   
3. Knurled screw on the brake lever
   Turn the knurled screw on the brake lever out to increase the brake force. Make sure that the side cuts for inserting the brake cable are not aligned after adjusting.
   
   
4. Brake caliper
   With an Allen key of size 5 you can adjust the distance between brake pad and brake disc. A smaller distance increases the brake performance and a larger distance minimizes the brake performance. Note however that too small a distance can lead to grinding noises.

Alternatively, you can use the disc brake adjustment tool to set the braking effect.

Swap the brake discs for the disc brake adjustment tool to achieve an optimal distance between brake pad and brake disc.

1. Pre-tensioning the brake cable holder
   Loosen the clamp of the brake cable holder using an Allen key of size 5 and pre-tension the lever until the brake pads sit firmly on the brake disc. Make sure that the brake cable is tensioned and sits correctly in the holders on the brake caliper, the Y-distributor and the brake lever. Then tighten the screw on the brake cable holder again.

Then you can replace the adjustment tool with the brake discs again.

• For checking, you can turn both wheels again and apply the brake. Check whether both wheels come to a stop simultaneously and abruptly.
  
• If necessary, readjust the brake caliper whose wheel came to a stop later.
  
  

Readjusting the brake caliper can cause the brakes to drag. If this is the case, you can realign the brake calipers. The brake caliper must be positioned so that the brake disc sits centrally between both brake pads. This ensures a friction-free run.

• Loosen both screws on the brake caliper using an Allen key of size 5. The brake caliper can now be moved sideways into position.
  
• Align the brake caliper centrally to the brake disc.
  
• Tighten both screws of the brake caliper again.
  
• Then check the friction-free run of the brake discs.
