Rear brake drum adjustment on replacement

Thanks all.

I went out and had it apart again.

The handbrake cable seems to be free. Probably quite old but the issue I had (before I started this nonsense) was that I needed to pull the handbrake almost vertical to get a grip. The drums seems perfectly free when it’s off and are well on when it’s pulled.

I tried the mallet, pump brakes, turn process for a while the. Put the wheel back on. Me giving it a good spin causes it to spin for about half a revolution before it stops. Still pretty well catching.

I’ll take it to the garage. Tail between my legs.

You could try slackening bleed screw on wheel cylnder, this will tell you if hydraulic pressure is holding the brake on with the flexis, abs pump or master cylinder questionable but if this makes no difference the faults inside the drum
 
Thanks bud.

The other side is perfectly okay so surely it can’t be a central source?

All I did was replace the drum on this side... Silly me!

I’m sure the garage will laugh at me and charge extra for the DIY attempt.

Unlikely hopefully!!!

You could try rounding off the outer shoulder on each of the corners of the shoes maybe this is simply grabbing the shoes too much? Is refitting the old drum an option?
 
Umm. The old drum went into the recycling metal section at the council facility... I don’t think it’s recoverable. I did think about it but I was overconfident!

You could also try swapping the drums side to side to then see if the trouble follows the new drum. What drum did you fit? Also never a good idea to just work on one side of the brakes.
 
Sometimes an option of 180mm shoes comes up but afaik this is incorrect as always 200 mm. Could the drum be wrong???

I planned to replace both. Now I’m scared to try.

The drums came from another A2 which had done a few thousand miles on them and was upgraded to disks I think. No reason to think there was a problem with them - very respected member.

Take the drum off again!. Then make sure the shoes are sitting correctly in the slave cylinder, the lower pivot and on top of the little teflon pads. make sure all the springs are correctly located and routed and the hand brake spring under its clip on the back plate. The hand brake operating arm must be on the inside of the shoes. Gently push each shoes in the slave to see if the other extends a little but do not go too far and dislodge the piston. Centralise the shoes by eye using the back plate as a guide. One possibility that has not been considered is a failing hub bearing, this would allow the drum to be out of position in relation to the shoes. Fit the drum back to front on the hub and tighten all 5 bolts so they all have touched the drum and then 1/4 turn. Now spin the drum and look for any visible wobble or sound. Then grab the drum top and bottom to see if any movement and repeat left and right. If all ok fit the other drum and see what happens. Take a couple of pictures of the brakes before you fit the drum in case there is something you have missed.
