I highly recommend getting flare nut wrenches for loosening the bleeder valve at the caliper.
They will prevent a potential major headache of using an open spanner.
Also;
A quick method for doing the clutch fluid.
- Remove the old fluid with the turkey baster.
- refill with new.
- pump clutch 20x (approx) & repeat.
Then do it again in a couple of weeks.
Not a pure drain & flush method but it gets most of it & it's easy.
