 |
|
Replaced all brake pads the other day for maintenance (zero issues with brakes). Pedal was soft. So bled brakes 3 times (first time rear to front "protocol." When that didn't seem to work, started driver front 2nd time-it was better, so did it again that way). Brakes seemed fine for a couple days.
I was having trouble with an oil leak from somewhere up top, replaced some things previously & nothing seemed to work. Did a re-build on the vacuum pump & that stopped the oil leak. THEN a couple days later, while reversing, the brakes almost completely failed. Pedal goes about halfway, but very little brake pressure happening. I immediately put it in drive, and they seemed fine. Couldn't find any info during research. (that was yesterday). Today, while in reverse at a store, brakes did the same thing. Tried pulling back into parking space & now they do that going forward. I shut off engine, pumped brakes 4 times, held it down, started engine, in reverse same thing happens with pedal (halfway down & extremely little pressure). Had to call a friend to drive in front of me going home, in case I couldn't stop (at least I hit a friend). The braking goes from that to normal.
Considering it could be the brake booster vacuum hose? (or the check-valve attached to it & the vacuum pump)?
The vacuum pump, just coincidentally?
Or??? HELP! |

Dude, this is an aircooled VW site. Very few people will have any knowledge about your watercooled car. I would recommend going to VW Vortex

With the electric parking brake it is often necessary to put the vehicle into service mode before replacing the rear pads.
Did you do that? |

What do you mean by "service mode"? (sounds like I didn't) |

^^ What it says.
Sorry but if you don't have the Service Manual, the right knowledge and a Computer to Read/Check/Write into your car, you should refrain to do service jobs in it.
It is the sad reality but your 2013 CC isn't a 1976 Dasher that most probably could be wrenched out with just a handful of handtools.
This is the case where a Dealer Job is faster ...and cheaper? |

If you don't know what "service mode" is, just admit it. Lack of knowledge is okay.
And apparently you are lucky enough to not know what dealers charge. Lucky you! |

Did you open the bleeder valves before you compressed the pistons back into the calipers?
If not, you will need to replace the master cylinder.

Not needed on this one. |

Wrong!
MY07 and I pay Dealer charges, still. Albeit in my neck of woods, not in California.
But my message still is: If I do not know, I shouldn't touch.
You can disagree, but you will keep having a brake problem still.  |

I'm looking for the knowledge from people that work on their own cars. Thanks, though. |

By that response you have told me you that you didn’t open the bleeder screws, yet you are having all the symptoms of a fucked master cylinder…
Good luck.

Explain why you are saying to open the bleeder screws before compressing the piston (and then I'll explain why that isn't necessary on this car). |

Compressing the pistons on the calipers on these cars send all the shit that accumulate in the lines, back through the master cylinder. It also has a tendency to invert the seals in the master cylinder. Having experienced this twice on customer cars, I have never done it again, but constantly get to fix it when someone else does it.
Any time i suggest that it’s an issue some asshole says I’m full of shit, and then they get to replace a master cylinder.
So… if you compressed the pistons without opening the bleeder valves, & you mysteriously don’t have pedal pressure, or it slowly falls to the floor, then you will need a new master cylinder.
Or, if you depressed the brake pedal beyond its normal range of motion after changing the pads, you might have torn the seals on any rust buildup on the unused portion of the bore, either way you’re probably looking at a master cylinder.
