OT...Polo rear drums
Im having some trouble with the rear drums on my polo...
Basically they were struggling to hold the car on a gentle slope so I replaced the shoes and bled the cylinders....
The cable is tight and only clicks on 4 clicks and it feels right...
But..the handbrake still doesnt hold the car back on a slope, and im sure the footbrake doesnt have any effect on the drums (makes stopping
tricky)...and the entire drum mechanism seems to be sticking a little bit... Basically if I roll up to a traffic light on the flat with my foot on the
clutch the car has a deffinative "stop" as if something is sticking...
I have an MOT comming up and need to try and get this sorted for that, and also so I dont have to worry about the car running away when I park
up...
I really hate working on drums...all those springs and mechanical thingies...the haynes manual isnt much help...it doesnt really show where the
springs should go etc...
Oh, its a 1996 VW polo...
Any thoughts?

Jack one corner up at a time and rotate the wheel. Do this for EACH wheel FRONT AND rear. This will till you which wheel is sticking and draging your
car to a halt on the level (probable a front cos you say the hand brake wont hold on a slope). If a front then you will need to free of the pads in
the carriers and the caliper slides. Unless you have a sticking caliper piston then you will need a new caliper. Fix as required.
As to the rear handbrake not holding, is the cable actually operating the shoe levers, is the cable seized on one side. Are the hand brake levers
seized. Have you checked the wheel cylinders for leaks?. VW/polo brakes are the easiest & most effectively simple adjusters there are. Get
something like an awl or long thin taper spike chisel & with the wheel of turn the drum until one of the wheel bolt holes is just past the top
vertical and looking through you should just be able to see the bottom of the spring pullled taper wedge adjuster ( where the spring goes through the
bottom eye) insert the spike carefully into this eye hole and lift the wedge. Remove the drum, inspect brakes for leaks, sticking cables and seized
levers. Replace faulty parts. Refit drum, set bearing preload & fit dust cap. Line up bolt hole. insert spike & pull down taper wedge until
shoes almost draging on drum, bleed brake if new cylinder & repeat process for the other side.
Beware of the Goldfish in the tulip mines. The ONLY defence against them is smoking peanut butter sandwiches.

Sounds like the cable is too tight -- slacken it right off and then pump the pedal to let the self-adjuster work then adjust the cable tension.

Waste of time waiting for VW adjustors to work , Do as jooley says but slacken off handbrake cable as far as possible . You should find the handbrake
will only come on 1 click with rear brakes adjusted properly
