Drum Brakes - Handbrake - Low Efficiency - Causes?
Basically had a mates mums Saxo in for repair today (just another excuse to use my ramps! LOL). She'd come out one morning last week to find a big patch of fluid down one rear wheel & all over the floor.
When I took it apart & I found that the friction material and clean come away from both the shoes in one of the rear drums causing the pistons to pop out the wheel cylinder & piss fluid past the seals.
So after cleaning up all the fluid, changing the shoes on both sides & replacing the leaking wheel cylinder (arent the springs a PITA to do on drum brakes! lol) I bled the system up - did all four corners - system was full of air it seemed.
Anyway I came to adjust the handbrake - set it to around 3/4 clicks.
Now comes the odd part - I can remember having my old Saxo donkeys years ago and I used to be able to yank the handbrake up & lock the rear wheels up no problem at any speeds lol - but on this Saxo even on stones outside my lockup the rear wheels wouldnt lockup when I put the handbrake on.
Could it be that the rear pads need to be bedded in properly first (I wouldnt of thought so mind) - what else could it be?

Hi matey - I was thinking that the faces of the pads and the inner drum probably need to mate to each other. Give it a little while - u could check that u have put it back together corret and that the handbrake mechanism really is moving the right parts in the right way

All fluid cleaned off perfectly prior to refitting - its doing it on both sides not just the one that was leaking.
Could the handbrake cables be stretching rather than applying properly?
