Ok, works a bloody treat.should have been doing it for years. Q: if you have front race lines, can you just do the cable tie and not bother to bleed? Obviously won't work with over mudguard setup. Q: will it work in my car? Maybe a brick on brake or piece of wood jammed in? Cheers
I've found it only works temporarily and in a short while you're back to where you started. Now I just try and bleed it right in the first place. Sent from my iPhone using Tapatalk
I reckon that under pressure the air dissolves in the brake fluid, just like CO2 dissolves in water under pressure. This gives a temporary fix but when the pressure is removed, with time the air comes back out of solution forming a bubble again and spongy brakes.
That's exactly what I've read. There's some scientific word for the air being absorbed by the fluid. Can't remember it but someone smarter will fill us all in. Sent from my iPhone using Tapatalk
So do once a month? Or night before a track day? But where would the air go? And if it just returns it must still be in the system and that would make it worse wouldn't it?
Yes but hygroscopy is the absorption of water by a natural attraction to it. We were talking about air dissolving in brake fluid. It's all down to Henry's Law
Before I bled mine properly, I was having to do it every night. Park in the garage and cable tie my lever. I also did the read using a bit of plastic pipe I cut to length (Jammed between brake lever and subframe). Became a nightmare so just methodically bled and raised various bits, until I was happy. Never had to do the cable tie thing again. Sent from my iPhone using Tapatalk
Why not buy a vac pump and pull the fluid into the system expelling all the air? Job done once,properly and cleanly! It's not a expensive bit of kit and can be used for lots of jobs,why take risks with brakes/lives?

That's the one that broke after one use for me. Hence why I now do it manually. The plunger part just completely pulled out Sent from my iPhone using Tapatalk
