I know with bicycles that (most) hydraulic brakes are all treated as modular units that you just swap out when failing, as opposed to servicing seals etc. You can get a fully bled lever, hose and caliper with pads nowadays for £30. To open that unit (if it was possible) and replace seals (if they were available) would be very time consuming and probably cost at least twice what the whole brake cost with labour and parts.


I'm sure there are lots of car parts that are similar. I know when we had a Ford a few years ago they already only sold certain parts as the whole unit and no parts to repair things.



We did have a main dealer want to swap a whole turbo unit out on our Passat a while back as they said it was not fixable. Part alone would have cost over £1000. A local independant changed the blown diaphragm in our existing one for £200. The main dealer wouldn't open it up to fix. They'd just swap the whole unit.
