  • Brake line lock can be widely used in various models which allows the front brakes to lock independently of the rear brakes via a switch. It also allows the front brakes to be locked and the rear brakes to be open, so that the driver to spin the rear wheels without wasting the rear brakes.
  • Easy to do a burn out by locking the front tires and releasing the back brakes with this system. Line locks are often used for burnouts by fully locking the front wheels and then engaging the gas pedal and disengaging the clutch pedal, this makes the rear tires spin but keeps the car stationary
  • Each kit includes a inline fuse connector, indicator light, snap-action switch, 2pcs 1/8-27NPT brass adapter and 3pcs mounting screws. High quality stainless steel valve assembly gives it strong sturdiness.Works with 12 -24 volt electric systems
  • Fully-enclosed epoxy-molded electrical coil makes it reliable; The attractive aluminum fin shell enables it to cool down; The wider lightweight base provides better mounting stability; besides, it has extra threaded port for brake line pressure gauge.
  • ATTENTION: This line lock is to be installed in the front braking system (for rear wheel drive vehicles) for drag race staging or burnouts. Alternatively, in the rear braking system for front wheel drive vehicles. This solenoid will not impede normal braking when installed correctly.

  1. Should not be engaged for more than 60 seconds
  2. The port marked "M" is the inlet. Connect the line coming from the master cylinder (through the proportioning valve in most cases) to this port. Confirm with the drawings in these instructions. Use teflon tape on the npt fittings into the solenoid.
  3. Use any of the other three remaining npt ports to go to the rear (or front depending on your application) brakes and plug off the remaining two open ports using 1/8” npt plugs. Use teflon tape on the 1/8” npt fittings.
  4. Connect the black wire from the line lock to a clean chassis ground, or directly to the battery negativeterminal if desired.
  5. Make all connections using the appropriate size lines, fittings and unions etc.
  6. If one line requires removal from the proportioning valve (some applications only), use an appropriate SAE inverted flare plug to seal the port. (no teflon tape is used on SAE inverted flare fittings)

Installation notes:

  1. Do not allow anything enter the braking system. Clean all connections and the surrounding area prior to avoid anything entering the system
  2. This line lock is to be installed in the front braking system (for rear wheel drive vehicles) for drag race staging or burnouts. Alternatively, in the rear braking system for front wheel drive vehicles. This solenoid will not impede normal braking when installed correctly.
  3. On any vehicle, the brake lights must function when the brake system is under pressure. If your application bypasses the OEM brake light switch, then another switch must be added to retain the brake light operation. A standard pressure activated switch can be installed in one of the unused ports of the line lock.
  4. Mount the solenoid securely to prevent brake line flexing which could lead to leaking or failure. Mount away from heat, suspension,steering and any moving parts.
  5. Always use a brake line wrench when securing fittings. Use a tube bender for bending lines to avoid kinking and breaking. Use teflon tape on NPT (pipe thread) fittings only.
