R50 mini one brakes are super spongey
Right so I bought a r50 mini one as a "cheap run about' it had sat up and had seized brakes as I thought that'll be an easy fix, "sure I'll just replace all the sliders" boy was I wrong! so far I've put all new discs, pads, a rear caliper, sliders and all new bleed nipples.
After doing all this I discovered the brakes where about as useful as Anne Frank's drumkit! As they are super spongey when driving but hard when the car is off.
When driving the brakes do harden if you pump the pedal to the floor a few times.
This is driving me crazy as I've bled the brakes so many times trying to sort this I could instruct Stevie wonder and ray Charles how to do it in my sleep!
Does anyone have any ideas what could be the issue with this turd?
I was thinking there could be a vacuum leak of some sort but no idea where to start looking.
Any help would be appreciated as I'm all out of ideas
Thanks in advance
