Hi. I need to replace my emergency brake cables on the 2004 R53 (85k miles in MN). The repair manual says to drop the exhaust to get access for this. I've got the interior stuff apart so have access to both cables where they enter the cabin. If you have tips/tricks, special tools needed and warnings, I'm all ears. I have the replacement cables already. The current cables are corroded and broken inside the rubber boot at the caliper. Thanks in advance for your thoughts and experiences.
