G – Installation boltsx3pcs
Step-by-step assembly:
Step 1:

Step 2:
Attach Part B to the matching side of Part A using the screws (D).
Then, fasten Part C to Part A with the remaining screws (D).
Step 1+2
Step 3:
Insert Part B into the hole in Part C.
Use the bolt and nut (E) to lock it in place.
Step 4:
The handbrake is now fully assembled and mounted onto the base plate.
"If you want to install it in your vehicle, you'll first need to detach it from the base plate.
This is easiest done by removing all screws (D)".
Then, use the installation bolts (G) to securely mount the base plate in your car.
About the included tool (F):
This plastic alignment tool helps keep all components – such as spacers – in place during reassembly.
It makes it much easier to guide the screw through the hardware when reinstalling.
Especially useful if the lever or master cylinder has been removed from their factory-mounted positions.
Plumbing the Hydraulic Handbrake
✅ Setup with Separate Rear Calipers (Recommended)
This is the most reliable and motorsport-friendly solution.
You mount a second caliper on each rear wheel – only connected to the handbrake.
Advantages:
– No interference with the main brake system
– No risk of backpressure or seal damage
– You can use both the foot brake and handbrake without affecting each other.
⚠️ Setup Using the Same Rear Calipers as the Foot Brake
If you want to connect the handbrake to your existing rear calipers (shared with the foot brake), we recommend using a brake distribution valve.
If you route the foot brake through the handbrake cylinder and use both systems at the same time, you risk damaging the front seal in the cylinder.
A distribution valve solves this problem.
See the diagram below for a suggested setup.
Potential issues without valve:
– Damage to master cylinder seals
– Fluid pressure build-up in the brake system
