hello, I am rebuilding the rear brakes on my Cinquecento. ( after 10 years of putting it off!)

Just to ask are the shoes self adjusting?

Yes, there's a self adjuster built into the shoes themselves. It's the bit that locates over the post on the backplate.

They're a bit crude, but they work.

Yes, stick them on and after fitting the springs and retaining clips carefully bash the shoes in toward the centre so they clear the drums ok. Then refit the drums - you may need to slacken the handbrake cable for this.

Once reassembled, pump the footbrake a few times and drive forward and backward a few times at a couple of mph using the handbrake to stop the car. This centralises the shoes and sets up the self adjusters.

You'll probably need to adjust the handbrake cable one last time. If you run out of adjustment, the handbrake lever itself is mounted on slotted holes, so the whole assembly can be slid back and forth to suit.

Ok all is back together! :dancin:

What a difference, my handbrake works! Also the car brakes pretty flat.

However when I pull the handbrake only one wheel locks.

Any ideas? or do they just need bedding in?

They should both lock really. Is the cable new?

Give it a little while to bed in and see how it goes, chances are it should be ok.

Just to add my bit, if they don't bed in you may need to check the internal drum diameter as it can have a dramatic affect as the handbrake quadrant goes past 90degrees when applied. A difference may have been caused by an imbalance you may not have been aware of.
