Line Lock System. Brake-Control Packages better know as a line lock system allows the driver to "lock up" the front brakes while letting the rear wheels spin free to heat up the rear tires in the burnout box for better traction down the track. Not only is it a great way to warm up your tires, but you can also use the system to prevent a manual transmission cars from rolling out of the staging beams at the starting line. How It Works. The SLP Brake-Control Package works by simply pressing the brake pedal and flipping the brake-control solenoid switch on. Remove your foot from the pedal, and the solenoid maintains line pressure to the front brakes until the switch is released. This saves wear and tear on your car's rear brake components from the old "left foot on the brake and right foot on the gas" method.

Complete Custom Kit. SLP Brake-Control kits are custom-fitted to the S197 Mustangs chassis, with no tweaking or fabrication required. It includes a waterproof electrical solenoid, an activation switch, plug-in wires, CNC-bent steel lines with correct OE fittings, mounting hardware, and detailed installation instructions.

Application. This SLP Brake-Control Package is specifically designed for use on the 2005 to 2006 GT Mustangs only. And is fully compatible with the factory anti-lock braking and traction-control systems.

  • Mine is on a toggle switch. Witch i like better than a push button A: Push brakes on with foot, switch toggle. Remove foot from brake. Your front brakes stay engaged until you switch toggle again Works very well !

    Great product

    Installation was straight forward with helpful color instructions. I have a kit like this for my F Body and both applications work perfectly.My only complaint would be that the toggle switch does not have a cover but a trip to the auto parts store solved that issue. If you have a right angle drill it is invaluable for drilling the mounting holes in the tight quarter of the mustang engine compartment.

    I had this installed while my car was in the shop for other things. The Tech said it was the best fitting unit he's ever installed. All the pre-bent tubing made installation a snap. I used it at the drags this last weekend and it worked flawlessly. My name is Fabman and I approve this message.

    SLP Line Lock Kit (05-06 GT)

    August 18, 2012

    Line lock works great. Just make sure the brass end of solonoid is on the line going to proportioning valve or it will not work. Goes faster with another person to help bleed brakes.

    Easy install, great bang for your buck!

    March 31, 2014

    The install was easier than I was expecting, kind of messy with the brake fluid but not hard at all. The pre-bent lines fit like a glove, wiring kit came with everything needed, and the instructions were easy to follow with pics. I strongly recommend being very careful when threading the new line into the block up front to avoid cross threading. After everything was said and done the kit works great, I wired it into my cruise control off button and used the switch it came with as an "arm" switch.

    An absolute nightmare, worked for a weekend then I flip the switch do a burnout and go to flip back, next thing you know the solenoid is permanently on. Drained it drove home messed around and thought I fixed it, three days later it locks up on me on the freeway!!! I drove home with no front brakes!! ABSOLUTE NIGHTMARE I thought I would let others shoppers know before they end up in this situation. Sometimes it works and others your getting towed home, stay away.
