Hi while my 172 is off the road I decided to clean everything up with the brakes. I fitted new discs and pads all round, braided hoses, cleaned all the callipers and carriers and replaced the fluid.

When it come to bleeding the brakes it would bleed up. I thought it could of been the master cylinder. After 2 week of Renault telling me I had an aftermarket master cylinder fitted to my car and them not knowing which one it was they ordered a choice of 3 for me to take mine in to compare. Went into the dealers when it was in for it to be the exact same as the one I had taken off.

I then fitted the new one and tried to bleed it with an eezebleed which seemed to work ok and remove all the air out the system but when it to trying them they still feel spongey. I then put about another 300mm of fluid through with no more air coming out yet the pedal still feels spongey and won't pump up. It's annoying me now because I don't know what it is.

Has anybody else hot any ideas of to what could be causing it cause I'm stumped.

I take it you have an abs model??

non abs would need you to bleed the caliper furthest from the master and work your way up to it. I.e back left - back right - front left - front right

Abs models will have a different sequence. On the old 21turbo you bleed both the front brakes like above but leave the back. Then with the ignition on then the abs pump feeds the back where you can bleed them off.

Hopefully someone a little more clio orientated can illiterate.

Yeah it's got abs. I did it in the non abs model sequence. I didn't know there was a different one for abs cars.

And if you get air in the abs module it is almost impossible to get out without purging it.

Try getting hold of a pressure bleeding kit and do it that way.

This is not correct for bleeding. You need to bleed the cross diagonal method of rear right, front left, rear left and then front right.
