After spending a few hours of trying to replace brake lines on the 300D, I hit a snag. As I was installing the left rear caliper, all was well until it came time to torque it down. The top bolt torqued fine, the bottom one just slipped and I noticed the threads on the bolt were rounded upon closer inspection. The caliper mount looks okay but using the bolt from the top mount, it just slides in and out.
Is this just a bolt issue, or is it the caliper mount? How much would it cost to source a new part and is it worth it?
This was my brother's car and its not in use so I'm prepping it to be sold or donated and at this point, I don't know if its worth the effort depending on the issue.
