Dragging drum brakes

[RS13]

Hi guys,

My brakes don't seem to be disengaging after a stop. It takes a few taps on the pedal and a few pulls on the handbrake to get them to loosen up, so the other night I got home and found that the rear right drum was too hot to touch, where the others were warm!

So I've stripped the rear right drum, cleaned everything (it has newish pads in there, the slave cylinder did have a bit of rusty crap in it, but the seals and internals of the cylinder look fine) and its' still doing it. Bled the brakes twice, no change. If it was the proportioning valve, wouldn't both sides do it? No blockages either.

I don't have much experience with drum brakes, is there something obvious that I'm missing?

Cheers!

for the price of some wheel cylinders, and the fact there was rusty crap in it. You may as well buy/install a pair.

Yes, the valve would affect both and opening a bleeder would release the pressure.
There must be something obvious or it wouldn't do it. The wheel cylinder's piston/s are stuck/frozen, or those mickeymouse self-adjusters are doing it, but usually they don't adjust enough. Never seen one that has adjusted it too tight.
E-brake too tight or self-adjuster assembled wrong is just a guess.

Check your return springs, if you have overheated the brakes too much the springs are also possibly poked.
