Jonathan Kay Posted April 28, 2018 Share Posted April 28, 2018 500 mL. Or 750 mL.Jonathan Link to comment Share on other sites More sharing options...
Martin7H Posted April 28, 2018 Share Posted April 28, 2018 JackI syringe the contents of the reservoir out and then use a litre of fluid and pressure bleed all four corners. Frequency every two years. Link to comment Share on other sites More sharing options...
SM25T Posted April 28, 2018 Share Posted April 28, 2018 Start the bleeding at the wheel furthest from the master cylinder. Look for the change in colour in the fluid in the bleed hose. Link to comment Share on other sites More sharing options...

Jonathan Kay Posted May 1, 2018 Share Posted May 1, 2018 Jack: There's a positive pressure kit and a valved nipple thing doing nothing in Garsington. Let me know if you'd like to borrow them.Jonathan Link to comment Share on other sites More sharing options...

Paul Deslandes Posted May 1, 2018 Share Posted May 1, 2018 Common advice is only to use the easibleed to pressurise the system and not as a reservoir for fluid as they can and do leak. Just keep the brake reservoir topped up during the procedure.And don't be tempted to blow all the old fluid out before adding new as it'll take forever to fully bleed it again . Just keep adding fresh fluid until any cloudy or mucky fluid stops coming out at each cylinder.Paul Link to comment Share on other sites More sharing options...
elie boone Posted May 2, 2018 Share Posted May 2, 2018 I always blow the old fluid out first and then bleed the brakes, i use a compressor and an old filler cap with a hole drilled in it. It takes about 1,5h from start to finish single handed. Link to comment Share on other sites More sharing options...
7 wonders of the world Posted May 3, 2018 Share Posted May 3, 2018 As mentioned before empty the old fluid from the reservoir with a syringe, refill with new fluid and bleed through, Link to comment Share on other sites More sharing options...
elie boone Posted May 3, 2018 Share Posted May 3, 2018 Just replaced a Girling mastercil for a AP master cil ( not the big one ) you do need a 5mm thick spacer as the hole need to be 35mm and the hole in the pedalbox is only 32 on an Imperial chassis. All the rest is ok, took me about 2h and between 500ml and 750ml didn't really measured. Link to comment Share on other sites More sharing options...
aerobod - near CYYC Posted May 4, 2018 Share Posted May 4, 2018 If bleeding the clutch at the same time as the brakes, I normally purchase 2x500ml to have enough for the job. As I use Motul RBF600 fluid, it is a very hygroscopic compared with most brake fluid in exchange for it’s 315°C (600°F) boiling point, so I bleed brake and clutch systems every year.
