Rear LH brake drum noise and overheating

[Bison535]

Before my recent MOT I replaced both sets of the rear brake linings and adjusted all round and checked Handbrake; MOT passed.
However, after driving a few thousand miles trouble free I now experience an occasional 'humming' from the LH Rear brake drum after a 20km drive and the Brake Drum gets very hot ( the brake ling must be contacting the drum !) If, when this happens, I dab the foot brake pedal the 'humming stops' for a period of time but then returns minutes later. I can create the same scenario if I yank quickly on the Handbrake whilst driving !??

I have since opened up the LH Rear brake drum and cleaned out accumulated dust and the linings, springs etc all look good as new ! I have also slackened off the adjuster ( more than the RH ) BUT the 'humming' and heated Brake Drum still reoccurs !!!! ?????

Any ideas of what steps to take next to overcome this issue much appreciated

I would check that all the springs are correctly fitted as it's quite easy to get a couple of them wrong.

also if you bought any new parts I found replacement hold down pins that where too long from JK and made the brake shoes sit oddly

should be as per pic

possibly easier with coloured springs

Check the wheel bearings for play too.

Can I be the first to ask where you can buy coloured brake springs

Hi Cobra88 great pics !

I also attach a pic of my recent new brake shoe fitting, springs etc look ok ???

Couldn't purchase the 'colored springs', only available in space

So, what next
