The car is a 1972 Hillman Avenger.  I would like to know the legality of the following two options please:
  1. If i fit a hydraulic handbrake into the rear brake circuit will this pass as a Parking Brake?
  2. If i fit a hydraulic handbrake with a seperate hydraulic circuit acting on seperate calipers
Neither options use cables or any other mechanical operation.

Cheers

 

Confused Nev :D

 

 

Hi Nev,

How about Two Seperate handbrake levers mounted in the vehicle? One Hydraulic and One Mechanical?:?

I Have seen this done.;)

True Fly off H/B needs the button pushing to lock rather than unlock.

A Fly Off Handbrake,

"Is" "Allowed" If fitted as standard,;) "Triumph TR4A", "Jaguar XJS", and maybye that "Hillman Avenger Tiger".;)

"Stealth" will be along shortly to put us out of our confusion.;)

Answers as follows;

1. No. Handbrake must be a separate Mechanical brake.

2. No . See above.

Your options are limited. The brake cannot be hydraulic,
and cannot be a "Fly off" handbrake.

Hi Kev,

why not a "fly off" handbrake? Jag XJS and others, fitted?

Some Rally Cars have a seperate hydraulic master cylinder fitted inside the vehicle connected to the handbrake lever, they use a fly off handbrake lever to allow the hydraulic handbrake to work.

The only difference between a normal hand brake and a "fly off" Is You press the button to hold the brake rather than it release.;)

ps; the latest electric parking brakes use an electric motor to operate cables.;)

Electric motors, Apparently they are OK as not hydraulic.

Ah, ok so how do the modern systems work that just seem to be a button and then i can hear an electric motor working?  Surely that would not be deemed mechanical?
