I ended up whipping the caliper off as it was the only way of removing one of the old pads which still had the sticky shims attached, and it was also easier to refit the shims with the caliper off, so have a 10mm hex key handy.

Yes, I bought a set of long punches when I needed to replace the door on mum's old Astra.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

Got some new pads to replace the rears on my 4S, but have not bought any anti-squeal shims...
Can I reuse the shims that are there? Keen to do so if possible as they are an astonishing £9 a piece from ECP and I presumably need 8...
I have used 3Mâ„¢ Ultra High Temperature Adhesive Transfer Tape , with success previously when I couldn't get a full set of ant-squeal shims in time for a project.
It worked absolutely fine and , if I remember correctly were available from a company called Viking.
Biggest hassle was getting the old adhesive off the shims.
Asked this the other day on the 997 section. The general consensus was they don't need doing every time.
The other thing that came up is copper slip is now no longer the preferred option. Use Ceratech also available from ECP instead, far superior.
OK, did my rear pads today.
I reused the shims/damping pads. They came off easily with a stanley knife, and were still a bit sticky so I did not use any adhesive, but actually one set had become detached anyway, and there is in my opinion enough pressure on the pad and damping pads even brakes off to render the adhesive un-necessary. All was quiet when I took it out for a test-drive...
If you feel the need to order any damping pads, then the 4S uses the two sizes of shims, four of each for per caliper. I think its the same for the NB cars. Given what they are, the cost is scandalous so see if you can reuse yours and save around £70-£80 per axle!
The pad change was straightforward- the hardest bit actually was getting the retaining bar out as it needed quite a wallop with a hammer and punch and I was afraid of chipping my caliper! Getting it back in was fiddly too, as you need to press down on the retaining spring to allow the bar back in. Make sure the cotter-pin hole is uppermost too...
I ended up whipping the caliper off as it was the only way of removing one of the old pads which still had the sticky shims attached, and it was also easier to refit the shims with the caliper off, so have a 10mm hex key handy.
Careful whacking the pins with a hammer, they are steel and can break/ crack the caliper where they pass through if you hit them hard.
Better to scrape as much dust and rust off and work them round with mole grips and penetrating oil, giving them a tap with a punch.
If well stuck cut them and get new from dealer or cheap from rockauto.
Yes, I put a coating of Ceratec on the pins when I reassembled.
I reckon the pins would have gone out much easier if I'd had a volunteer to hold the retaining clip down. Once I'd got the hang of it the other caliper was much easier. It was also easier using the biggest punch I could find, which was only slightly smaller in diameter than the pin.
Yes, I bought a set of long punches when I needed to replace the door on mum's old Astra. They've been useful on a number of jobs since, having the right size really makes a difference and they're quite cheap.
