Or rather, bleedin' brakes....
It was easy to do and easy to make a mess.
This cost £2 + postage, arrived 2 days after ordering and for the money is an effing amazing investment.
Had the luck of my 11yr old to gently pump the brake pedal whilst i watched the fluid ooze out of the bleed screws.
Only advice (other than what's already printed on the box) is DON'T turn the bleed screw more than just enough to allow the fluid to escape. Even learing that trick the hard and messy way, I still didn't manage to do any corner of the car without spilling a few drops.
If you really have no jack, axle stands or ramps, with patience and dexterity you can just about still bleed the brakes. Not good advice to do it this way, but for those in that situation, thought I'd throw that in here...
