[Healeys] Unbalanced Rear Brakes

[Tim Ward]

Hi Mark
After a lot of research and discussion I think what happened to you is also
my problem.

I would try to do the job myself but I don't have enough space on the side
of the car in my workshop to change the oil seal. So it is off to my
restorer, Peter Ellis in Northampton, next week to be sorted out.

Hopefully with a similar good result

Thanks for your reply

Tim

Tim,

I had the same problem two years ago in the tri-carb.  Right rear also.
In my case there was a fine film of oil on the swept area inside the drum
but none visible outside with it still in place.
On removing the half-shaft I could feel a little 'noise' in the bearing and
also see a tiny amount of run-out in the hub. As a result the oil seal had
worn, causing a tiny leak . .  but big enough to reduce braking efficiency
by about 75%.

A new bearing, oil seal and gasket fixed the problem.  At the same time I
replaced the linings on both sides and had them radiused to match the drums.
BIG improvement.

Hi Team

Your usual good advice will be greatly appreciated.

My BJ8 failed its annual Test this morning due to very unbalanced Rear
Brakes. The Front brakes were virtually perfect.

 

The Brakes were tested on a rolling road, front first and then the rear. The
Left Rear showed normal Braking efficiency with normal pedal pressure.
Right
Rear showed below normal braking efficiency with very  hard pedal pressure.
Used together the Right Brake was almost non existent, and therefore the
very unbalanced result.

Any thoughts as to what might be the reason for this? 

In the past they have always been a little unbalanced, but within the
acceptable range.

Looking forward to your replies.

 

Thanks

Tim
