I have an original, ie old (2009?), SLX disc brake set up on my bike and want to bleed it. Can anyone recommend a bleed kit off ebay which they’ve had success with?

Try epicbleedsolutions.co.uk

epicbleedsolutions but as it doesn’t need a cup thing for the reservoir then just get a 50ml syringe and some aquarium air stone tube from a pet shop.

I would agree with the others on epicbleedsolutions.co.uk I used a couple of syringes from ebay and a short piece of PVC tubing from B&Q. Personally I would recommend using a toe clip strap or similar to hold the lever in place – frees your hands up.

There are lots of videos on Youtube showing you how to bleed. I recommend this one:

The only problem you might have is if you’ve lost all the fluid and have then squeezed the lever a lot. This results in thousands of tiny bubbles which can take several bleeds to get them all out – lever will go rock hard when you’ve fully bled the system.

Just as good as Shimano and half the price. Just as good as Shimano only it’s green rather than pink (just in case you have transparent hoses)

Don’t be soft getting bike specific mineral oil, LHM oil is the same stuff

Eg http://www.ebay.co.uk/itm/320846598309?redirect=mobile

epicbleedsolutions.co.uk also here, worked perfectly and cheap.

Not sure how this is 1/2 the price, it’s £4.99 (£39.92/l) for 125ml ( when the proper Shimano oil is £16.99 for 1l from CRC.

Epic kit is spot on- you can easily make your own tbh but it just comes down to how you value your time.

That’s true. However, for most people will never need anywhere near a litre of mineral fluid. Mineral fluid isn’t hydroscopic (unlike dot fluid) so you only need to bleed when you crash into a tree or pop the pistons out when you’ve got the bike in the car.
That said I am the only one of my group of mates who ever has a bleed kit. Could be worth getting a litre if you’re likely to be fixing your mates bikes as well.
