The TCI RollStop 861700 is a universal brake line lock kit with a 12VDC electric solenoid, solenoid mount, push button switch, inline fuse connector, and mounting hardware. The waterproof 6061-T6 aluminum design uses 1/8 in NPT female inlet and outlet ports and a precision solenoid valve rated to 3000 psi while drawing only 1 amp of current.

Installed in line with the vehicle’s front brakes, the RollStop lets the driver hold front brake pressure for burnout use. Pump the brake, apply the RollStop, and release the brake pedal to keep the front wheels locked. If additional pressure is needed, the one-way valve allows pressure to be added through the brake pedal.

The kit includes the solenoid, microswitch, red powder coated switch mounting bracket, inline fuse connector, and mounting hardware. TCI notes the RollStop can be installed without brake system modifications, and application-specific versions are available for certain Camaros and Mustangs. Warranty coverage is limited to 30 days for racing use and 90 days for street or strip use.
