The Big Bang

Into the garage and started up the Spyder - early 4200 cambiocorsa - and once idle had settled down pulled it into reverse which produced one h&ll of a bang from below somewhere. Reversed out gingerly after pulling the down paddle to calm things down a bit and all seemed OK on a short drive to another storage place (to lubricate hood locks).

First time this has happened. The car usually sits still for a few weeks between each exit but the difference today was that the car had been left in N all the while. I usually leave it in 1 and flick it into N before starting.

Any ideas? Sticky driven plate?

The car/clutch is ‘quite frisky’ until everything is warm so cold reversals out of this narrow garage are a nail biter.

Brake pads are likely but it depends on when the bang was: Selecting gear (not brake pads) or moving off (probably brake pads).....

Garage is dry - heated a little by a well sealed double lined wood burner flue passing through!
Do not think pads as the car was dry when parked plus it did not sound or feel like pads which I get a lot with our outdoor Renaults. It happened immediately I engaged R not later as I brought the revs up to move. Can’t remember if the car moved enough to jerk the pads as I pulled R.

However as not much braking was done in the trip I will check the discs for witness marks which ought to still be there. Pads would be a relief!

Will be the handbrake shoes welded to the drums that suddenly let go. I would have them checked.

What they all said then. If it was clutch it’d have been the instant you engaged gear.
