So my rear brake was fine until I went and got my chain and sprockets replaced. Then my rear brake would not function as it normally does and when I stopped driving I touched my rear brake disc and it melted my glove because it was so hot so I figured the rear brake was just constantly being applied. When I asked the mechanic about it he said that my rear master cylinder would have to be flushed and so I bleed all the old fluid put new fluid and the same problem was still occurring. I asked the mechanic what he thought and he said I may have to disassemble my entire rear master cylinder to unclog the small hole that allows the break fluid to flow back into the reservoir. Any ideas or how to disassemble read break master cylinder to unclog said hole?

I doubt a master cylinder issue if you had no issues before and now after the chain and sprockets there is.
