Aragorn Posted April 21, 2009 Share Posted April 21, 2009 i would imagine you'll need a couple of litres of fluid to successfully flush all the old fluid through. Quote Link to comment Share on other sites More sharing options...
ebdesignDEFENDER Posted April 21, 2009 Author Share Posted April 21, 2009 2 liter? Quote Link to comment Share on other sites More sharing options...
freeagent Posted April 21, 2009 Share Posted April 21, 2009 I doubt the capacity is much over a litre but as the others have said, you'll want to flush a fair bit through it to ensure you've got clean fluid all round..... Quote Link to comment Share on other sites More sharing options...
Les Henson Posted April 21, 2009 Share Posted April 21, 2009 I doubt the entire systen holds much more then 250ml. I wouldn't buy more than 1-litre to clear the whole system on any L/R. Les. Quote Link to comment Share on other sites More sharing options...
Aragorn Posted April 21, 2009 Share Posted April 21, 2009 theres gorra be more than that, the pistons and calipers are huge, i'd think theres probably close to 100ml of fluid in each front caliper... Having an extra litre isnt really a big deal anyway. I'd rather have the extra, sealed sitting on the shelf, than running out half way thru bleeding it.

Les Henson Posted April 21, 2009 Share Posted April 21, 2009 The calipers may be huge, but there is almost no cavity in the caliper body. The pipe connection goes straight to the base of the pistons, so with the piston fully compressed - as for instance when the pads are new - there is almost no space between the base of the piston and the bore that it slides in. The capacity of the system would therefore be dependant on the condition of the brake pads/shoes I would suggest that if you are going to flush the braking system and at the same time remove dirty fluid/rubber dust, then the wheel cylinders and caliper pistons being in a fully compressed condition, would greatly help in doing the job better/quicker.
