Astra 2008 1.6. (39k on clock)
Rear brakes squeal when driving in dry or wet. Noise really high pitched and stops when brake depressed. Know its the rear as it also stops when handbrake lightly applied.
Cleaned and copper eased to no effect.
Pads still have plenty on them although a bit shinny and pock marked.
Have new pads to put on but are the discs likely to be ok?
Do all rear calipers need a rewind tool (Lucas?) as piston doesn't appear to have holes? Cant get piston to retract to allow new pads to be fitted.
Any help appreciated.
