Generally, discs need replacing every second set of pads.

That seems to be the way, though the garage generally tells me I've
been "lucky" as modern discs and pads are intended to need replacing at
the same time.

I do my own maintenance and only use a garage for a few things (welding
a sill, replacing a cambelt and replacing a dual-mass flywheel) that
would have cost me more in time off work to do it myself than for them
to do it.

In 30-odd years I have only replaced discs on two cars, both due to
slight warping - I have never worn a disc to the minimum even on cars
that have had numerous replacements of pads and mileages of 160,000+.

Are garages pushing unneccessary changes for profit?

I blame the passing of asbestos for discs wearing out fast .....

Mine don’t wear out any faster than they did with asbestos was used.
lucky you ...on aveage every second or third set of pads you need discs
these days ....



My problem has been rust on the surface of the discs leading to
potential MOT failure. It is hard to know just how much rust will be
tolerated. The difficulty I had replacing replacing pads and discs was
getting the piston to retract. I had to buy a special tool on ebay.
