Bench bleeding?
I recently fitted a new master cylinder to my Rover 25. Researching the job before hand there was a lot of advice about bench bleeding, before fitting. I rigged up a bench bleed kit with various pipes and jubilee clips I had, and spent about 15 minutes slowly pumping through on the bench, until all the bubbles were gone. On the car I bled out all the old fluid using a pipe with a one way valve at each wheel station.
I was glad I did the bench bleed first as it took many pumps on the bench to get rid of all the bubbles, and the fluid was recycled back into the reservoir. I also spoke to someone who works in a garage who said bench bleeding is not necessary. Thinking about this later, they probably have advanced pressure bleeding systems or are not too concerned about running litres of fluid through as it would be charged. Any views on whether bench bleeding is necessary when fitting a new master cylinder etc?

is that a clutch or brake master cylinder?
I don't think I have ever changed a brake master cylinder but it is not in my opinion required for the clutch. macafee2 |

Brake master cylinder. It was the first car one I’d done, swapped out MCs on motorcycles before, but a lot less to bleed there.
