Hi everyone....

well my series iii is almost there. new suspesion all round, body replaced or welded up, new paint job and wiring!
Here's the thing!
I've replaced 3 of the wheel cylinders, all the shoes and a couple of lenths of copper pipe (no visible problems with the master so left it alone)

Bled the entire system (4 times now) following the correct sequence and still the brakes are so non existant that even when i pump them they only get marginally better!
there's either a major air lock in the system or i'm missing something fundamental.... any advise guys?

Giles
 
Giles,

Bleeding LR brakes sucks ! You are not alone in your suffering. I do not have the answer for you although in the magazines and online searching through google brings up various ways of doing it. I tend to get the professionals to do it if possible. However, I am going to have to a bit of bleeding myself shortly as part of some major work on a S2a and I am going to try something that I came across on the web:-

Instead of using the brake pedal and master cylinder to pump fluid out of the brake wheel cylinder nipples, you get a syringe and rubber tube of the correct dimensions and inject clean fluid into the nipple remembering to keep the master cylinder from over flowing as you pump new fluid in. It's brilliant in it's simplicity and lovely in it's world-turned-upside-down approach. If you decide to do this yourself I would be happy to hear your lessons learnt, I won't get to mine until I have rebuilt a gearbox.

Regards,
 
Hi Giles

I came across this and I think it is what Ned was on about.
Anyhow let everyone know the outcome and good luck with the brakes.
There's loads of info on the web, and some of the guys in the forum have great, inforative sites.


I have been using a easy and clean way of bleeding the brakes on my Series III which works really well and does away with a helper having to pump the pedal like mad.
All you need is a short tube about 12" long and a syringe with a capacity of 20 to 30mls. Firstly drain most of the brake fluid from the resevoir. Fill the syringe with brake fluid, open the bleeder nipple, connect the syringe/tube to the nipple and inject its contents into the brake line. Next close of the nipple and hey presto! your brake will be rock hard as all the air has nowhere to go but out through the reservoir. Repeat for each drum as per your workshop manual (remember to reduce the fluid content in the reservoir after each brake is bled).


There is sufficient fluid in the syringe to fill the brake line and partly fill the resevoir. A quick and easy solution to an awkward job.
