Hydraulic Disc Brakes

I am looking to replace the brakes on my Kona Dr. Dew vintage 2008. It currently has Shimano MB-485 brakes. I haven't been able to find instructions on how to bleed them. The kits they sell for Shimano hydraulic brakes don't work for this brake. There is no place to attach the bleed cup on the brake lever. Should I get another set of hydraulic brakes or just get a set of mechanical brakes.

Bikes: Too many. Cannondale SuperSix, Trek Remedy 8, Trek Crossrip+ get the most ride time.

For older Shimano brakes you can bleed them by opening the reservoir cover and pushing fluid out into a rag from the caliper, then gravity bleeding back down to the caliper by dripping mineral oil into the reservoir.

Most shops will have the Shimano professional bleed kit, which includes a hilarious/awkward tool that is basically a clamp with a rubber pad on it with a hole and a threading for a bleed cup that you fit over the reservoir cover, then bleed like their more recent brakes.

If you replace them, I recommend staying hydraulic. Shimano is probably the best value--their cheapest are totally fine; the Deores are a fantastic blend of performance and value.
