Should I get a new bike

Hi all, I’ve been trying to figure out a good bike set up for months now.

I currently have a very cool rock lobster that’s probably 10-15 years old with nice but equally old parts. Aside from just generally needing a tuneup I’ve had a lot of problems with the brakes.

The brakes feel less effective and powerful than even a Lyft bike’s brakes. I’ve tried replacing pads and having them looked at to no avail. The only final candidate is the cables.

Anyways, I have an opportunity to get a BMC team machine SLR 02 frame with a 105 groupseg and the stock wheels for around $1300. This would include an upgrade to hydraulic disk brakes. My rock lobster has sram force derailleurs so technically it would be a downgrade but the sram groupset is very old. I would use the other parts from my current bike to complete the build.

Just hoping to get some input. Do you think this will fix the issues I have and be a worthwhile upgrade versus trying to fix this bike?
