I have a 240 with standard brakes and they're spongy - help!
We've bled them and also had them bled by a local garage under pressure. Still no improvement.
If I pump the brakes it builds pressure. The smaller reservoir (toward the front of the car) sploshes about a fair bit when I pump the brakes.
I've checked the driver footwell and pulled out the carpet to see if there is any fluid leaking - nothing. Lines have been checked. Lines have also been independently crimped (at the rubber section) to see if it's a line issue.
Local garage thinks it might be the proportioning valve causing the problem, but I'm not so sure.
