MOT failed.. how much will it roughly cost to fix?

uhm alot... shock absorber might be around 60 factory replacement nothing special. im guessing.... exhaust leak might be rusty so they would have to replace alot of it so depends how bad it is. any were from 80 to like 140 id say with new muffler as well hoping ur catalytic converer is alright and oxygen sensors... fixing a break depends who is doing your work? are u or is a mechanic? mechanics charge like 80 a hour and then that could be sum work put into it plus parts... cant say on parts cause we dont no wat could be wrong. could need adjusted. could need new springs and stuff. that side may not work at all with just hitting the brake. could need new cable.
