190 brake bleeding

[Big peter]

Hi guys I have a 190 2.6 high line
I have been trying to bleed the brakes, I have tried wazir bleed and the good old fashioned method, the mrs sitting in the car pumping the brakes and me shouting.
They didn't work, I can not get the fronts bled.
Am I missing something. ?

How old are the flexible hoses?

Is the master cylinder ok?

 

[Big peter]

Flexi's are all fine, no leaks
I have thought about master cylinder, but the backs seem to have bleed up ok.
Confused

 

[stwat]

Have you made sure you have fluid in both chambers of the fluid Reservoir ?

BTW, I was thinking the flexis could be collapsing internally rather than them leaking.

 

[Big peter]

Stwat how would I know that is happening ?

There would be little or no fluid coming through the bleed nipple, is it not worth getting a garage to do it with a proper pressure bleeder?

Gunsons ezybleed is a good cost effective DIY bleeder, bleed nipples can also get blocked.

Pela suction (oil draining) tool apparently works - and without denying easy access to the reservoir to top up as the Gunson one does.

Does the car have ABS? Some ABS systems are a pain to bleed.

You don't need to top up with the Gunson, fluid is held in a separate reservoir and pushed under pressure into the MC chamber.

I forgot about that.
When I've used a Gunson bleeder I just put the fluid directly into the car's reservoir to prevent the spillage on removal. Hence having to disconnect the cap to replenish. PITA for me given the reservoir is accessed through a slot smaller than a letterbox.

Cheers guys I am going to try a pressure system to see if that will push things through, if not replace the master cylinder first.

What are the symptoms - in what way wont it bleed?
No fluid coming through but stiff pedal? Same but with limp pedal? Other?

I had the same issue, was fluid only in one section of the reservoir, if you fill the reservoir right to the top, then it will flow over into the other part, and as you bleed make sure it does not empty.
