Title: Re: Handbrake ? Post by: Manky Monkey on November 07, 2010, 01:19:41 PM One of the reasons I went for the VW Golf calipers for the Reliant disc brake conversion -they incorporate a mechanical handbrake. The caliper piston sits against a flat plate. Under normal braking, both the plate & the piston are pushed out to apply the pads to the disc. When the handbrake's pulled on it screws the backing plate out of the caliper body, carrying the piston with it & applying the brakes by mechanical means rather than hydraulic.
Many race cars use hydraulic line locks, which use a valve to trap brake fluid in the hoses -apply the brake as normal, turn the valve & the brakes stay on. Doesn't comply with MSVA requirements cos it's hydraulic, not mechanical. |
