Brake cyllinder rebuild

[stx133]

After having new front disks and pads fitted due to wear and a small warp, found the new disks warped within 2 months (i do about 4,000km/month)
the mechanic who fitted the disks machined them (1.5 thou apparently) and off i went again (no charge). 1 month later warped again.
The culprit, worn seals in the calipers not releasing properly, causing rubbing and overheating of the disks.
The mechannic is recommending a seal kit for the calipers, 2-3 weeks x-europe. he is also going to replace the disks and pads as a warranty issue at his cost to fit.

--> is a seal kit / rebuild the best/most cost effective option. would aftermarket upgrades be available at a reasonable cost?

--> does anyone else get this kind of service from a BMW factory trained local shop mechanic at reasonable price. is there anyone in melbourne (around Coburg) who is looking for a mechanic that they can trust.

That is the most cost effective way, with OEM parts

NO way to do any upgrade here. You already have the big stuff on the e34. Next step is 750 4-pots or M5 brakes. Big money.
