[Healeys] 100 brakes

[greylinn at ozemail.com.au]

Michael assuming you have some resistance after pumping the pedal, jam the pedal down hard and leave it at least overnight, preferably longer. Do this repeatedly & you will find the pedal comes up. Don’t ask me why, but I’ve done this several times with my own and other people’s cars, and it works!

Cheers

We are having a very difficult time adjusting & bleeding the brakes on a friend's BN1. 

The car has recently under a full ground up restoration so things like brake lines including flex lines are new, seals in the brake cylinders are new, the master cyl. is new, etc.

We bleed the system so many times different way that I have lost track. 

We have adjusted the free play to assure that the plunger is able to return to the full "off" position.

When we adjust the operating rod to achieve the specified 1/8" free movement at the pedal.

We have adjusted the brake shoes to have a very slight drag at rest.

Our issue is:

Excessive brake pedal travel before the brakes begin to be effective. 

Pumping the brakes temporarily improve the pedal travel issue, which we think indicates air still in the system.

We are not having any leaks & the reservoir port is functioning correctly, IE: no locking up of the brakes.
