11 best line lock kit

A line lock kit, in the context of automotive replacement parts, is a device used in high-performance vehicles to temporarily lock the front brakes while allowing the rear wheels to spin freely. This is particularly useful for situations like drag racing, burnouts, or other situations where you want to keep the car stationary while allowing the rear wheels to spin.

Here's how it works:

  1. Brake System Control: A line lock kit is typically installed in the brake system. It allows the driver to isolate the front brakes from the rear brakes.

  2. Activation: When activated, the line lock temporarily traps the brake fluid pressure in the front brake lines. This effectively "locks" the front brakes, preventing the vehicle from moving forward.

  3. Rear Wheels Free Spin: With the front brakes locked, the rear wheels are free to spin. This is useful for burnouts or other situations where you want the rear wheels to move independently.

  4. Release: Once the driver releases the line lock, the brake fluid pressure is equalized, and the brakes function normally again.

Line lock kits are popular among drag racers and car enthusiasts who want to perform controlled burnouts without having to hold the brake pedal down manually. They can be installed in a variety of vehicles, but they are most commonly used in high-performance cars with powerful engines.

Please note that the installation of a line lock kit should be done by a professional or experienced individual, as it involves working with the brake system, which is a critical safety component of any vehicle. Additionally, the use of line lock kits may be subject to local laws and regulations, so it's important to ensure compliance with any applicable rules.

User questions & answers

Question: Can this work as a hill assist? Meaning, when it is engaged on a hill an released does it prevent a manual type vehicle from rolling back on a hill
Answer: It will work as a temporary brake but it is not good as a parking brake. While in use it will have a small draw on the battery thus over time it could kill the battery. Additionally a parking brake is designed to be mechanical as a seperate system. This means it wont fail due to leaks or loss of pressure. In short the answer is no.
Question: How do you adjust it to make front wheel brake tighter
Answer: Yes, it's not designed to be activated for very long, 10 to 30 seconds. It will most likely overheat if activated for over a minute or two.
Question: What adaptors will i need for a 1986 ford mustang gt convertible
Answer: The solenoid is a npt thread ..i went to stainless steel flexible lines so i needed a inverted 7/16 3an fitting for my application. Running from the master cylinder to the line lock and back to the brake line junction block
Question: Can this be used for a parking brake replacement
Answer: Yes, normally open until energised

Notes

  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)

User questions & answers

Question: Can this be left on overnight without burning it out I want to use it instead of the parking brake
Answer: You don’t need to adjust it, the only adjustment is with your foot on the brake pedal. How it works is you press down reasonably hard on the brake pedal, activate the line lock and release the pedal, due to this being plumbed into the front brakes it will retain the pressure and hold the front brakes while the rear is released. So all of your adjustment is dependent on how hard you push the pedal. Wanna do a rolling burnout, push lightly on the brakes and then activate and release pedal to just hold some drag on the brakes. Once you release the button it will release the pressure and to reactivate you would have to start over or do a quick brake jab and hit the button, but I don’t suggest you try that.
Question: Does this have 2 inlets and 2 outlets
Answer: It depends on where u put it. It’s easiest to take it apart first and take your lines/fittings with so u can match up exactly what u need. Sometimes u can even buy the lines already made up with the correct fittings and u just use the tubing bender to shape them the way u need them
Question: So I see 4 ports..... 1 inlet and 2 outlets for front brakes and one for the rear which is optional
Answer: No it cannot. It will only hold the brake as long as you’re holding the button

User questions & answers

Question: what color is light accessory
Answer: Not supposed to, selinoid is not meant to be held over 1min. Could potentially wear out/damage the internals. It would technically work, but I wouldn't trust it, plus a constant 12v to keep it locked would probably drain your battery.
