Basically, my Nissan Leaf has a problem with the parking brake (drum brake) rubbing and causing massive heat build up in the combined drum / disc assembly.
I have taken it into 3 garages and all 3 have failed to fix the problem. I reckon they have taken a look at the caliper and found no issue and not looked at the drum brake at all. All three have not charged me for them taking a look at it which also suggests they didn't look too deeply at the problem. The third mechanic actually told me that the Leaf doesn't have drum brakes!
Anyway, I am kind of forced to take my car back to the third garage as after picking the car up from them the last time, the parking brake is completely seized up and I can't drive a mile without the disc becoming too hot to touch. So basically I have come up with a list of things I want done to try to fix the issue. Here is what I am going to hand into the mechanic tomorrow:
Can you please go through this list on both rear wheels to rule out the drum brakes causing the problem. Thanks.
Would adding a link to one of the video tutorials be a step too far?!

- Remove the disc brake caliper and then the combined disc / drum.
- Inspect the drum for corrosion and for contamination of the shoes.
- Check the shoe retracting springs and retainers.
- Take the shoe off and clean up the backplate contact points on both the shoe and the backplate. Grease appropriately.
- Chamfer the leading and trailing edges of the friction material.
- Disconnect the handbrake cable and check it for free movement.
- Check the handbrake mechanism operates the shoes freely.
- Refit the drum and check the wheel bearing play.
- Check and set the drum brake shoe adjustment.
- Check and set the adjustment of the parking brake cable by the rear axle beam.
- Check the disc brake pads are free and caliper sliders are not seized.
