My handbrake is buggered but i'm tryin to narrow down the reasons, i tightened the cable in-car but it seemed to made it worse or no difference. i'm going to have a look at the rear brakes and see what they're like soon. if i will go ahead and replace them do drums need replacing really?
thanks

i'm not quite sure what you're sayin, you couldn't sort out the handbrake yourself? were you adjustin the cable?
you didn't really help me out lol :p
they got drums and shoes for both rear sides for like £40 on ebay lol.
 
Drums only need replacing if scored on the contact surface,cracked or otherwise physically faulty. Check that everything is operating properly with drum removed and shoes visually OK. Diagnose if not. A leaking slave cylinder is a possibility, especially if the fluid has not been changed as recommended, which really is a false economy. If so replace BOTH, and the shoes. If one is gone the other will soon follow.

The brake fluid is above min so i dont think it's been leakin but it hasn't been replaced for well over the recommended time
the front brakes work though and the car stops very well when the engine is on.
Is the slave cylinder on the gearbox?
Thanks for the reply
 
I think the slave cylinder in question is the one that actuates the drum mechanism. As for your problem, take the drums off first and have a good look. It could be a buggered handbrake auto-adjuster mechanism, or a seized component. Another failure mode is if the wheel bolts are too long, they can catch on the internal springs and cause them to snap.

If it is the shoes, then it might be worth replacing the drums too, I think a pair can be had for less than £20. Otherwise, check for scoring, and run a DTI gauge check to make sure the internal shape is still circular (I have very little idea how to do this, hence why I would just renew the drums)

The drums seem oval on the inside as it scrapes once during a full rotation and rest of the rotation it is very free, and a spring seems to be damaged, not sure if it was cos of a long wheel bolt. :eek:
The shoes seem to have wear on them too.
I will check the auto adjuster thing too when i replace the drums, i thought you had to get to it by takin the shoes off but read in the manual there's a cap behind the wheel you can take off to reach it! :slayer:
I replaced the brake fluid today and checked the left drum today.:cool:
do you know where i can get the spring from?
 
When you fit a brake drum, have someone press the brake pedal then tighten the mounting screws. This makes sure the drum is properly centered.

My Seicento hand brake is weak. The drums pads and and hydraulics are fine and the cable also seems fine. I believe it will need new hand brake levers at the top side of the rear brakes.

These are cheap to buy and tend to distort over time so perhaps best to start there before changing drums or pads.

If you are replacing the drums do the shoes as well (the adjusters are on them). Make sure the cylinders work by getting someone to touch the brake pedal (they dont need to do much otherwise they will pop the cylinder). The springs etc may be available in a fitting kit from somewhere like halfords/partco etc.
I have done the rear brakes on 3 Mk1 puntos now and all of them have needed cylinders.

The cylinders are good, i popped 1 side not too badly then my gf exploded the other side! :bang: i pushed the rubber bit in nicely though. she helped in the end though... i guess (y)
 
lucky you, i have not had one where i havnt had to replace the cylinders, as a thought if your bleeding the brakes then might as well do the clutch as well.
