Noise From Rear Brakes
Posted 13 March 2018 - 09:21 PM
Jacking the wheels off the ground and pulling handbrake on a couple of notches then rotating the wheel by hand you can hear and feel the shoes getting tighter in one spot with a ping from the springs. I wonder if the shoes are moving laterally but by design their does seem to be lots of sideways movement. The ends of shoes wiggle round in the slot on the slave cylinder but that must be normal.
I do have some fairly new budget mini spares minifins fitted and wonder if these are the issue. Possibly they are out of true? (In will try fitting the original drums). It seams as though when the brake is applied their isn't even pressure giving rise to movement in the shoes but I don't understand what would cause the loud creaking.
I don't think it's a good idea but should all the internals, hand brake mech and springs be greased?

Sure they're in the correct holes, can't go far wrong? The bottom one near the slave cylinder has Spring sections at either end, with the long wire biased away from hub. Top Spring ihas the long centre wound section.
Wonder if they are just old and knackered?

if you look in hour Haynes manual it shows the correct way and you will have then the wrong way so the rub. they are offset so they clear the hub.

Look at the hub you will probably see a clean groove all the way around where the spring has been rubbing on it.

Ok I was somewhat sceptical about above advice as i was certain the springs were right. Went out to garage tonight and yes they are as they should be. Thought I'd check the other side and low and behold bottom Spring was upside down and yes there was a grove in the hub, genuine lol moment. The Spring is half worn through (new springs ordered). Weird as I was convinced noise was from opposite side.
Quick test drive and seems ok. I would be so chuffed if this has sorted it, such a small but annoying thing that distracts from the fun of driving it and I just ran out of ideas.

Been there, done that - it was in 1963 if my memory serves me well!
