I need to bleed my rear brake & I've got Shimano Deore M615 Brakes but have no kit as yet.
I've done a quick search and it's only come up with stuff like this:

The problem is that they seem VERY stingy on the amount of mineral oil that they provide.
For £15 you only get 50ml of mineral oil.
Does anyone know of anywhere where its better value for money ?
This is advertised as for cars - will this work on Shimano Deore M615's with no problem ?
Yep. It's the same stuff
Okay thanks. Better than paying £5 for every 50ml of mineral oil.
Do NOT use anything other than genuine Shimano mineral, They are NOT all identical.
50ml is more than sufficient for a brake bleed and you shouldn't be doing it often enough that cost becomes an issue.

Have you bled them and run out of oil, or are you just worrying upfront? From memory the oil in those kits that goes in the syringe at the top can be rebottled and reused if not needed - you just need enough that it never sucks air in. Don't reuse the stuff you let our the calipers, though.
LHM for the oil.
To get consistent bleeds on the rear brake I put the bike in the wheelie position (let gravity do the work) obviously adjust the lever so the bleed port faces upward. Assuming you have the Shimano funnel, bleed up from the caliper making sure you have completely replaced the existing fluid with new, always shut the bleed port off when there is a flow of fluid going through. Then bubble bleed. Works every time for me, bleed done once in 10 minutes and no crying on forums about how shit Shimano brakes won't bleed! I have a secret easy technique for the notoriously difficult Avids, it's the u-bend at the lever that causes most of the bleed problems!
You can use medicine syringes (for giving babies medicine) or the ones for refilling printer cartridges (same thing) and generic clear fuel line hose (available from all auto-factors for pennies). Which slips over the syringe ends and onto the bleed nipples. That's what I use for both Shimano and Avid, albeit with Avids you need the threaded bleed port adapters, which again just push into the fuel line hose. Epic bleed kit for a few quid 😉

Just worrying upfront. I just thought that 50ml is not going to go very far.
in all likelyhood it won't need a full replacement. just put the bike up with the line running vertical, loosen and turn the lever so it's horizontal, take off the little cap. flick the line all the way up and pump the lever, the liquid will bubble and drop out of sight to a lower level, top up with a syrunge until it's up to the top.
Shimano used to do a litre bottle. I've had a bottle of it for longer than I care to remember. Despite spilling nearly half of it I've probably still got about a third of it left. Total overkill bottle size wise.
If you're worried buy another £5 worth/50ml.
I've used that Epic Bleed Solutions kit and it's fine. Loads of oil left over after bleeding front and back.
A litre for £16, will last forever, buy some syringes on ebay for pennies and a length of aquarium air pump tubing.
A pair of well abused brakes, 2 years past when they last needed a bleed, will still not use 50ml when you do a complete flush and bleed.
You'll still be left with oil in the bottle. (unless you spray it all over the place and pour it all over the floor)
And Shimano techs use LHM when they run out of the shimano stuff. It's not the same stuff but works 99% as well. Some of the other mineral oils can make a mess of your brakes.
But what km79 linked to will do the trick.........
