bleeding brakes, soda stream brake fluid

[emery1990]

Yer you'd have a hard pedal if you had a vac leak. Wouldn't of thought ignition would matter, no electrics to the braking system is there? Part from the brake fluid level indicator.

I hope I don't this issue when I test mine   I've just bled them and left atm

I had this on mine the problem was the nipples on the rear calipers are halfway down and air gets stuck above them take the caliper off and clamp the piston and hold the nipple so its the highest point and try again i got loads of air out

Did you try this?

Right bled the brakes today with the help of Mr B.

Checked unions and for leaks and found none.

Does seem I have sodastream fitted somewhere in the car as there aren't normal bubbles but looks like the brake fluid is carbonated?

That normal? Superfine bubbles in it that could only be seen when strong sunlight was directly on the bleed tube.

Think there must be something letting in a tiny amount of air somewhere?

 Not too sure how I progress from here.

Have you pressure-tested the system, with an air-hose to the reservoir?

Have you opened each line at a time and walked away and left it for 1/2 hour?

Swapped the master cylinder for a known-good one?

I left my system pressured at 20psi for about 40 mins, came home and all my fluid from my eezi bleed bottle had gone!!

Maybe put a line on where the fluid is then come back later to see if it's dropped, even if it's a few mm then you know there's a problem.

Looks like I may need to rebleed my rear brakes again, my pedal doesn't firm up.

Have you pressure-tested the system, with an air-hose to the reservoir? It has been pressure bled by Kwik Fit, that may mean nothing though.

Have you opened each line at a time and walked away and left it for 1/2 hour? You mean take the bleed nipples out? No.

Swapped the master cylinder for a known-good one? Yes I have

Not sure how you pressurise the brake system without specialist equipment?

There is defo air in the system just need to figure out from where and how to get rid of it.

Ok so found a slightly moist T section which I am going to replace.

I shouldn't need to but does anyone know if PTfe tape is ok with brake fluid?

There seems to be a tiny little air leak some where. Now I have the fabby job of trying to locate said leak.

EZI-Bleed kit is cheap and uses the spare wheel to pressurise the system.  Worth a shot to help find your issue.
