Re: Espace IV - rear brake caliper removal with worn disk?
....I had to refit the worn pads - outside one is actually OK, but the inside one is pretty worn so I need to find a solution soon.
If the pads are wearing unevenly as you say, the caliper isn't free to slide on the sliders, you need to sort this out while you are in there.
If your car uses the same alloy rear callipers as the Laguna 2 proceed as follows....
The 7mm allen bolts (Slider pins) that the caliper slides on pass through rubber inserts in the caliper, remove the rubber inserts from the caliper and you will probably find a build up of corrosion (oxidisation) in the hole where the insert sits, this corrosion forces the insert to close up and grip the allen bolt which stops the caliper sliding as it should. Clean all of this corrosion from the hole until you are back to nice clean alloy, then apply some grease, make sure the rubber insert is clean and apply some grease to it before refitting. When fitting the 7mm allen bolts (slider pins) make sure they are nice and clean and put a smear of grease on them. when it's all back together you should have a nice free to slide caliper.
If the piston is turning freely you just need to apply more pressure to it as you turn it to get it all the way in.
