With PCCB's the recommendation is to change pads at half worn to minimise heat soak into the brake fluid.

Suggestion · Original poster
My front pads are down to 6mm and I seem to remember reading that pads should be replaced when half worn on pccb equipped cars , does anyone know the original thickness please ?

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.
16 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.
0 acknowledgements have no verified action link; they do not establish a repair result.

My front pads are down to 6mm and I seem to remember reading that pads should be replaced when half worn on pccb equipped cars , does anyone know the original thickness please ?
Cannot help on the thickness point but I had mine replaced at 8 years old this year and even on a low mileage car there was clear deterioration in the surface condition of the pads. There is marked improvement in feel now.
With PCCB's the recommendation is to change pads at half worn to minimise heat soak into the brake fluid.
I found that with the PCCB's at this point, it was the integrity of the remaining pad material that was a concern ... with substantial thermal stress of the pad material which had clearly deteriorated due to excessive heat.
This was transformed when I fitted Surface Transform discs ... they ran much cooler than the PCCB's and preserved a much longer pad life with further reduced brake dust as a consequence.
Recently had new pads fitted. Remembered this thread and thought I'd measure them. Curiously the new pads are only 8.5mm from surface to backing plate. I guess inflation, materials cost and profit margin have driven new pads to be thinner...

Are these pagid ?
arcamalpha said:
Yup. Pagid P40 3W FF. Not sure it's a PCCB-specific pad but it is the same model as the ones that came off.
Therefore will only last 4.25 mm until half worn
If not a PCCB pad maybe it should not be replaced with the same not a PCCB pad ?
It's not the percentage pad depth that is the issue ... it's the residual pad depth that is recommended to minimise heat soak ?

Not sure!

Totally agree. So new pads being thinner is a shame. But they're still a good chunk thicker than what came off!
This is a source reference. Confirm exact model applicability in the original material.
