Live axle brake diagram.

Recommended Posts

G'day fellow sevenistas, somewhere in my garage is a page with the diagram I now seek again, bloody Pixies probably shifted to a safe place.

Anyway does anyone have a diagram, Haynes style, of the rear brake assembly from the Morris Marina axle, or a link to a page that I could download, just had a knuckle busting curse laden hour or so rolling about on the garage floor, figure that something isn't in the right place, it really shouldn't be this difficult.  

Any assistance gratefully received, many thanks.

Thanks for the info.

The diagram supplied by bjw is interesting in that it shows the springs on inside and outside of the brake shoes, which is how I had mine fitted until yesterday, where upon I fitted the spring at the hydraulic actuator end to the inner side, with much cussing and mangled knuckles,

I haven't had a chance to see if this has had any effect on the hand brake performance, got to late in the evening, needed some scoff and beer, will be back on the floor when I get home later.

Hand brake effect has been very poor, not much retardation when hauling on the handle, so am looking at anything which might be out of whack. I should have taken a photo before dismantling it, hindsight.

And bjw, if you could send the section through to my e mail I would be very grateful. Thanks.

Yes, but Tony Weale's book doesn't actually show the Ital version. The return spring next to the cylinder in the Standard layout is shown behind the shoes, not in front as per the Ital and there's no support plate fitted in the leading shoe.

Cheers

Hauling on the handbrake will never provide much retardation- they only need to be 16 % efficient to pass MoT at gvw 525kg. Once you have clean shoes correctly sprung in drums which are clean and score free all you can do is axjust the cable correctly. I got a marginal improvement by replacing the handbrake cable which had marginally stretched even though only ever used at MoT test. My old tester, now retired, used to want the lever pulled hard from outside the car to get the best result - hardly practical but never an issue at MoT on mine.

I have the Tony Weale book and have noticed the variation in a the diagrams of the hand brake mechanism, I now have both springs in board of the shoes, but as the diagram "bjw" posted shows the spring at the piston position outboard, perhaps I need to assemble it in that manner, and see if I can get a better adjustment with the cable, which is free in the sleeve, 

I have deglazed the shoes, not that there appeared to be anything unusual with the surface, a quick rub over with some ali oxide paper, and also inside the drums, I haven't had a chance to get back to it since then, but we have a long weekend here, so hopefully more work before the man from the ministry checks it over.  

Thanks all for your assistance, much appreciated.

Nigel.
