Supposed to have them, many don't reinstall them, a mater of controversy.

Well, they are a bugger to fit
if you haven't got the knack.

Easy peasy if you think it through though thumbs up

Two bee hive springs are fitted to the rear brakes but none on the front. My WSM shows a photograph of the rear brakes as Fig M.22. on page M.14.

Here is one supplier that shows them. Bull Motif. Probably others such as ESM as well. Good luck.

Cannot remember fitting them before , only the pin type with washer and spring , they were missing when I restored car 7 years ago and I never noticed.

I usually use a very wide bladed screw driver and push in add twist. Still at best it can be tedious.

Hi,

What is the purpose of the bee-hive springs?

Once the shoes touch the drum, the drum controls the alignment of the shoes. The pull-off springs should also try to) pull the shoes against the "stops" on the back-plate, and allow the shoes to "sway" (but only inwards) to follow the drum.

If the drum is distorted outwards, it will try to pull the stop pin through the spring retaining washer ... the pin can only move one way (towards the centre of the axle) - unless it stretches or snaps.

Anti-squeal?

PS. The thought crossed my mind that a broken half-shaft will allow the rear wheel to lean (either way). I'm not sure (semi and three-quarter floating axles) if a broken half-shaft will allow the wheel/hub/halfshaft assembly to wander off if the half-shaft snaps. Has anybody been there? If I had to bet, my money (but not a lot) would be on the wheel leaning a bit, but otherwise staying in place. I prefer fully floating hubs ... like on my Land Rover

I don't put them back on mine, it's been a point of debate for years so to each his own. Broken half shaft on a moggy isn't going anywhere, including tilt, the bearing holds it in.

Perhaps the springs are there just to aid in drum removal. The other possibility is to help keep the shoes centered since the cylinder slides allowing the bottom shoe to rub.

Axle bearing terms relate to what role the haft shaft plays. Semi floating - the shaft supports the weight, holds the wheel upright, transmit power, the shaft rides in bearings. Three quarter floating - the shaft holds the wheel upright, transmit power, the weight is carried by the hub/bearing. Fully floating - the shaft transmit power only, the hub has inner and outer bearing like a front hub. Typically, semi floating requires that the shaft also holds the wheel in while the others are retained by the hub.

For those who are not familiar with the terms.
