EYE_WHY Posted February 7, 2006 Share Posted February 7, 2006 So I bled my brakes acouple weeks ago and they did feel firmer and didn't sink as low but now they are back to where they were before (if not worse). The pedal sinks a couple of inches and only gets firm (which is still pretty mushy) about an inch from firewall, kinda scary! I don't think my reflexes are fast enough to yank on the e-brake if I had to so I really want to get these fixed!! So I've established that bleeding the brakes doesn't fix the problem and I've checked hill holder which is fine. Where should I look next? I know master cylinders don't usually go out but is it worth a shot? Link to comment Share on other sites More sharing options...

Where should I look next? I know master cylinders don't usually go out but is it worth a shot? I had the EXACT same problem with my legacy... master cylinder and new rubber lines cured it... unfortunately I didn't do them one at a time to see which actually fixed it, but if your rubber lines are checked, cracked, missing an outer layer, here is why I would suggest replacing those first: those rubber lines are multi-layered, and if the outer layers flake off or whatever, when you step on the brake pedal it can cause the rubber to "balloon" out in the line, and be just like there is more volume in the braking system, causing your pedal to have that mushy feeling.... personally I replaced the rubber lines because they were old, and the master cylinder because I felt that's what the problem was, after bleeding my brakes several times like you did Link to comment Share on other sites More sharing options...
Johnnyboy Posted February 7, 2006 Share Posted February 7, 2006 I would think, that if you're positive you got all the air out of the lines and you have NO leaks in the lines when the brake is pressed (you've checked the fluid level and for spots of fluid on the floor right?) Then i think it has the be the master cylinder, either it's not getting the vacuum it needs or the inner plunger is stuffed. Link to comment Share on other sites More sharing options...
EYE_WHY Posted February 7, 2006 Author Share Posted February 7, 2006 Ya, no brake fluid on the floor. How much were the new lines operose? Link to comment Share on other sites More sharing options...
Hank Roberts Posted February 7, 2006 Share Posted February 7, 2006 My story's here, I won't repeat myself. http://www.ultimatesubaru.org/forum/showthread.php?t=39459&highlight=brakes+sink I can confirm bad brake hoses can balloon and be part of the problem. But read the stuff about the brake booster and also the comments I quoted from other places as I found them. Took me 8 months. May you be luckier.
