Jamar Hydraulic Park Lock For Brakes
The Jamar Park Lock is designed to temporarily hold brake calipers in position by applying hydraulic pressure. It features a 1/8 NPT threaded connection and brass fittings (note: fittings are not included). This unit is suitable for users seeking a compact, easy-to-install line lock option that can be integrated into various brake line configurations. Its straightforward operation makes it a popular choice for maintenance bays and drag setups where a reliable parking hold is needed without specialized hardware.
PQY Front Brake Line Lock Kit
The PQY Front Brake Line Lock Kit is designed for drag racing and hill-start scenarios, offering compatibility with 12-24 volt electric systems. It can handle high pressure spikes up to 1000 psi, enabling a quick brake hold at the start line. The system is engineered for easy operation, allowing control of both front and rear brakes through a single solenoid valve. This makes it a versatile option for racers seeking reliable line-lock performance without complicated installation.
Manual Brake Lock Hydraulic Line Lock
The Aramox Manual Brake Lock uses hydraulic line pressure to secure brakes for parking or maintenance. It is designed for universal compatibility with cars and trucks equipped with disc or drum brakes and supports standard line configurations. Built with precision metal components, the unit emphasizes long-term durability and stable pressure retention under repeated use. It suits users needing a rugged, reliable lock that can withstand frequent engagements in a workshop or on the track.
CNSPEED Front Brake Line Lock Kit
The CNSPEED line lock kit is designed for versatility across models, supporting 12-24V electrical systems and handling up to 1000 psi. It includes an epoxy-molded coil for reliability and an aluminum housing for cooling and durability. An extra threaded port for a brake line pressure gauge provides visibility for monitoring brake force, while the main function remains simple: fully lock the front or rear brakes to secure the vehicle on a hill or starting line. This makes it a strong choice for racers and enthusiasts who demand both performance and monitoring capability.
EMPI 3155 Hydraulic Park Lock
The EMPI Hydraulic Park Lock is aimed at VW-based platforms like sand rails and Baja/dune buggies, though it can be utilized in other applications where line pressure can be harnessed to hold brakes. It uses hydraulic pressure to keep the brakes engaged, and operation typically involves pressing the brake pedal to set the lock and then engaging the Park Lock lever. The unit is designed for straightforward use with minimal setup, making it suitable for off-road builds and lightweight racing contexts where reliable brake hold is essential.
Buying Guide: Key Purchase Considerations
- Compatibility: Check brake system type (disc or drum), vehicle electrical system voltage (12V–24V), and whether the unit supports 1/8 NPT ports or requires adapters.
- Pressure Tolerance: Look for line locks rated to withstand high psi spikes (around 1000 psi is common in high-performance kits) to prevent leakage or failure at the start line or during holds on inclines.
- Installation Ease: Consider units with straightforward mounting, included fittings, and clear release mechanisms. Some models offer quick-release features when the pedal is reapplied.
- Reliability and Durability: Aluminum housings, epoxy-molded coils, and durable metal components influence longevity, especially under frequent use or in rough environments.
- Monitoring and Safety: Some kits include gauge ports or monitoring options to observe hydraulic pressure, aiding in prevention of over-holding or brake line stress.
- Brand and Support: Reputable brands with documented compatibility notes and customer support simplify troubleshooting and parts replacement.
When selecting a hydraulic line lock, align the choice with the primary use case—daily maintenance parking, drag racing, hill starts, or off-road scenarios. Always confirm thread size, port availability, and whether fittings are included or must be sourced separately. While performance figures like psi rating are important, ensure your installation adheres to local safety standards and vehicle-specific requirements.
