Hi Pelicans,
Although plenty of material left on my 10 year old brake pads... decided to upgrade to Porterfield R4S’s after reading so many positive comments here.
When I removed the old pads from the front calipers unfortunately saw this!
About 50% of the rubber dust seals had become embedded in the back pad surface. I think I may have put squel deadening material on there… don’t remember.

So…. it looks like easy new pad/sensor replacement has now turned into draining brake fluid, removing frt calipers and installing new rubber seals. Right ??
Doesn’t make any sense not to replace what remains on all 4 frt. piston outer seals??
Fortunately back caliper seals are fine.
Also - wasn’t planing putting anti squel on the Porter-fields. If you have these pads w/o antisquel… any issues? Thoughts? Pls let me know.
Thanks,
JT
