if there's no evidence of a leak the I'd fit a new master cylinder.

It may well look ok but you have no idea what condition the internal seals are in.

You feed beefburgers to swans.

I may have been speeding Mr Policeman but [a] I live for the 306 and [b] did you see that dog? omfg

Would you say that could be the problem then?
I have bled each corner a few times so I sure any air would ne out or least enough to reduce this. Although there has been no improvement from bleeding so far!


A mate said might need to bleed the abs block???

Yeah that's what first thought was!
Then could be servo, and vacuum pump?
Is there any way I can diagnose which one is to fault with out having to buy all ne bits?

No all standard!

I am not so bothered about the job just don't want to replace something and it not be that and have to do another one. End up replacing all the system could I put a 6 servo and ms cylinder on?

Ok had another look.

With the car OFF ~
The pedal pumps up and goes rock hard and wont go to the floor.

Once turned ON ~

Will start to pump up and then slowly go the floor.

Would this mean it might not be the MC as it should be loosing pressure when off surely?

Re-bled mine today, put a litre of fluid through the lines, no change , gonna order a new master cylinder on Tuesday when I get paid, will let you know if it fixes the problem as mine seems similar to yours

I had a similar problem to this so thought I'd post up how I have hopefully solved it ,

First I got a brand new Master cylinder off Lukejenks off here , bench bled the new master, fitted it, re-bled the system and no change ,

Started thinking then it must be the Servo but could not find any leaks so must be trapped air, last night put another litre through still no change ,

Done loads of research on the net so decided to remove all brake pads and push pistons right in, on the drivers rear the piston would not wind in for some reason, so I put one brake pad back in, removed the dust seal and then pressed on the brake, the piston came out far enough for me to clean it, there was a fair amount of crud around it but cleaned up ok and piston was in good nick tbh, the piston then wound in with no problem,

I then attached a pressure bleeder and put fluid through at 20 psi while also pumping the pedal, this got a tiny tiny air bubble out of the drivers side rear, more research led me to unbolting the rear calipers and positioning so that the bleed nipple was at the highest point, re-bled again,

More research led me to trying to bleed diagonally, i.e rear left, front right, rear right, front left, the haynes manual says front left, front right, rear left, rear right, so again pressure bled at 20psi while pumping the pedal and voila! I heard a big splutter of air come out of the right rear, test drove the car and pedal seems back to normal and brakes great again

Don't know really what has solved it tbh, could have been the new master cylinder as the old one was leaking slightly where the reservoir joins, although any air pulled in here would surely just rise back into the reservoir, could it have been the sticking piston? , more likely it was just because my system was being a pig to bleed not helped by me having Wilwoods on,

Gonna order some decent fluid now to change the cheapo stuff in there now, any suggestions? I have tried Ate blue but was not that impressed although better than the crap I have in at mo, think I will put another litre of the cheap stuff through and then try summit decent like motul rbf 600

I have really faffed around with this and used about 12 Litres of fluid since Christmas -about £60 quids worth , just made up to have solid brakes at last
