- M4 Bleeding
Hi All, one for the masses please….
What do I need, if anything to reuse an avid bleed kit to bleed M4’s. Forked out enough on the Avid kit without another 30 quid for the Hope one.
I suspect its very little from a quick Google but I’m not sure if there’s an adapter etc that would make life that much easier?Posted 6 years agoOnzadogSubscriber
For hope, I use a syringe and a bit of pipe over the bleed nipple. The syringe was a few pence from the vet (50 ml). I like to bleed from the bottom up. I also have the avid bleed kit but It’s not worth trying to adapt it. It is worth following the dame method for bleeding though.Posted 6 years agomattjgSubscriber
Don’t buy the Hope kit, you dont need it and the bloody thing was dangerous in my experience – bad seal between bottle and tube resulted in fluid squirting across the garage.

It’s a 10 minute job after the first time. If anything you get a tad OCD about it. Make sure to get the calliper/pads/rotor nicely lined up.Posted 6 years ago
Just bleed it top down in a conventional way. No kit needed apart from a bit of tube and a jam jar
Means nothing to me sorry. Having only had Avids I only know the painful and very time consuming method using expensive kit, video, instructions, swearing, calliper rebuild, etc etcPosted 6 years ago
Fozzy – I am sure that vid is enough but… ( assuming mini lever not tech)
Remove top of master cylinder
Put tube on bleed nipple, end into jam jar on ground. Pull lever. open bleed nipple, hold lever in . close bleed nipple release lever and repeat – every 3 or 4 pulls of the lever top out reservoirPosted 6 years agoTreksterSubscriber
Having tried the top down, hose and bottle on the nipple technique and failed to get rid of the air in my rear calliper I relented and took it to my lbs.
His technique was from bottom up with a syringe and whilst pumping in fluid he tapped the calliper. Sorted within minutes and still OK 4mths on 😆

It is best to have some fluid in the jar to cover the end of the hose to create a seal to start withduirMember
Fishtank tube from a petshop, fresh bottle of 5.1, a spanner and a empty plastic milk carton. Just make a hole in top of the carton and feed the tube in and attach to bleed nipple. Perfect results with hopes using gravity alone, absolutely no need for expensive kits. To ensure all air gone make sure bleed nipple is highest part of the caliper during bleed, adjust levers/reach for maximum throw and only do 2 pulls of lever before each refill of master cylinder. After a while no more air…..perfect. If tech levers make sure to do extra bit from hope video. The latest hopes rarely need a re-bleed.Posted 6 years ago
