Thought I had covered everything in preparation for road trip to South of France tomorrow. Full service, MOT , error code checks etc etc. even fitted a new battery. Wife nipped into town last night and came back saying there had been a `tremendous grinding noise' from rear of car but this had then stopped. I had a drive around and nothing obviously wrong. Jacked rear end up, wheels off - nothing amiss. Went to bed thinking it was probably a stone, as we driven over a re-laid road the day before. Woke up today with that niggling feeling I had to get it checked. Rang my indy and he fitted me in at short notice. Drove car there ~8miles. No problem until I turned into road next to garage when all hell let loose - thought someone had a grinder in the boot. Car up on ramp - wheels and drums off. Found brake shoe flopping about in driver's side rear drum The head in the spring loaded securing pin had corroded and popped out. Phew! Close call - hope my luck continues for the next 2000miles and 2 weeks. Apologies for any grammatical errors.
