Biesheuvel - Hydraulic Park Lock (line Lock)

Jamar's hydraulic park line lock uses brake line pressure to hold your brakes. Typically, to install this, you cut the brake line that leads from your master cylinder to your rear brakes and install this in that brake line. To activate the park lock, just push the brake pedal down with your foot, then push the park lock button down. To deactivate the park lock, tap on your brake pedal with your foot and it will release the park lock. Do not use this line lock on hydro or power boosters. There is too much pressure on the lines. It is only intended for manual brakes.

This universal park lock is great for highly modified off road rigs where a long travel suspension or aftermarket axles prevent you from using a conventional cable type parking brake.

Uses DOT 3, DOT 4 or DOT 5.1 brake fluid. not suitable for silicone based brake fluid.

Both the inlet and outlet are 1/8" NPT pipe thread so you'll also need to purchase adapter fittings for whatever type of brake line you're using.
