Handbrake — logbook Toyota Sprinter Trueno, 1991

Yesterday before midnight I changed the handbrake cables. In general, everything is elementary there, but the soured bolts, as usual, make you think about how to twist them painlessly.
The first folded bolt turned out to be on the exhaust pipe and figs with it, but the second part numbered 47601A fell off, scoring it, laid the cables in their places and in the end found that it was not possible to tighten the handbrake in the cabin, too much free cable? Where else is it regulated?

Removing the muffler, along the way gouging a hole in the catalyst, inside everything is covered in soot.
