2000 Eurovan PCV/breather options #evcrepair

#162444

The diaphragm inside my 2000 EVC's PCV/breather is warped and leaking oil and the part is NLA. Anybody have one they are willing to sell or have advice on how to get around this issue.?

From my experience spongy feel is often air compressing in the hydraulic system.. Bleed and refresh the fluid.

Noel, Sam and mac m,

Thank all of you very much for your guidance and suggestions.? Mac m, Thank You for your photos, they were very helpful.

I removed the vent cover and vacuumed the vent with my shop-vac using an adapted length of flexible 1" tubing that fit into the vent tube.? It was clean.? I try to keep the vent bug-free with a small piece of aluminum screen door mesh around the end of the external vent tube held in place with a large zip tie.?

I removed the utensil drawer along with the lower cabinet shelves and its rear panel.? The problem was obvious, the flex tube from the sink drain assembly was hanging loose from the OEM "U" support attached to the back wall.? I routed the flex tube back through this support and secured it there with a zip tie.? Added another zip tie around the wooded support at the rear of the cabinet (right behind the rear of the drawer) so that the tube now makes a gradual descent from the drain down to its attachment to the vent assembly.? Water drains great now!

My water lines and their clamps all look to be in good condition, no evidence of leaks anywhere.? After seeing the actual water lines, I agree with Sam that these should out-last my EVC.? I've had experience with this exact type of tubing.? My parents were in the restaurant business and this type of tubing is commonly used in fountain soft drink dispenser consoles to supply carbonated water.? Can't remember having to replace one of these pressurized lines, ever.? So my EVC is ready to go on vacation.? ??

Thank you again for all of your help!

Wigen- No codes, just the feel of "sponge" instead of solid hydraulic system as it was before they installed the new front pads and rotors.

Have you checked the ABS codes with a vw code checker for ABS ?

If you pump brake peddle and hold down does it make a difference ?

Hi everyone- Vanpira remains in the shop- turns out they bled 2 cups fluid right rear but then "didn't keep track of the other calipers" as the proceeded. Brakes improved somewhat but pedal still way spongy compared to before job. In another group I got a reference to a procedure for bleeding 93 Eurovans with ABS that involves having to "press the lever of the pressure regulator in the direction of the rear axle when bleeding the rear brakes" Anyone know if this applies also to 1997?

Thanks for feedback Phil B re Europarts pads. Good to know. The whole "it's the pads " doesn't make sense- if it was the pads, why did performance improve (somewhat) after yesterdays re-bleed? I really think they are just unwilling to believe it takes that much fluid! BTW, did you do anything with a "Pressure regulater" at the rear axle, or is that not a "thing" on our newer generation vans? It was referenced in bleed instructions for a 93.? Also- same reference was calling for cycling the ABS pump... again,I've not seen that in bleed procedures for a 97 or newer so maybe an older generation ABS & does not apply to 97-2003?

Thanks again,
Peter L & Vanpira

Pads not your problem. ? Are there codes lodged ??

ive used semi metallic pads from EuropartsSD (and others) before, never had an issue also had many vehicle and always done my own brakes.

Thanks everyone for ideas so far- Shop re=bled with pressure bleeder & used more volume of fluid this time. Finally able to lock up brakes briefly in panic stop mode, but pedal is still wayyyy spongier than before front pads/rotors replaced & almost compresses to floor. Was a very firm normal pedal with little travel before this. Dhop is convinced that the semi metalic pads I got from Europarts SD are the prob & want to get a new set to try, I'm ready to say whatever & let them go ahead even though thismakes no sense to me & it still feels like air in the lines. BTW, when I did the panic stop/lock up,after the ABS kicked in & I eased up a little on the brake pedal it "Bumped back" against my foot pressure (or burped back?)- Thought I remembered that also as an inbdicator of air trapped in lines.? Curious if ANYONE with a Eurovan that had "spongy pedal" after a brake job "Cured it" by removing and replacing their new pads. ANYONE? I've not found any reports of this in any threads on Eurovan brakes. Thanks everyone!? Peter L & Vanpira, still hoping to hit the road....

Daniel- Not hearing any hissing noises as described in some of the videos, but booster will be on my suspect list if this morning's high-volume bleed does not solve it. Also have seen some references to proportioning valve problems, but not clear on whether that's with our EVC's or other vehicles, nor how to diagnose &/or deal with them.

Brake booster!  That’s it!  Mine is ‘95. You can’t just bleed the brakes if you have one, you have to do something else or brakes will be spongy/not be able to do emergency stop... not to mention downhill stop. Happened on my van when brakes were worked on by non-knowledgeable people.

Droppin bombs-Thanks for the idea and video link.? I wonder if the booster would be "disturbed" by the front brake work and bleed process? All was good til the passenger front caliper stuck. Of course everything works until it doesn't ;-) Shop says they will redo the powerbleed tomorrow with more fluid volume sacrificed & if that doesn't work we'll be looking into other culprits :-)

Brake booster?? Not sure about your year... but my 1993 needed one.? Made a lot of difference with braking as well as idling at stop.

Re: Front pads & rotors replaced- spongy weak brakes in 97 evc #evcrepair

#162429

Dan- Thanks! I was wondering if there was a special device buried in the system, such as a “pressure regulator” you mention, but the online threads of how-to-bleed-your-EVC-brakes for years around 1997 don’t reference any special technique or such an item. There’s the ABS, which is a sort of pressure regulator, but I’ve not seen a special approach to bleeding the ABS system. Just pressurize, start at passenger’s rear, and work forward - driver’s rear, passenger’s front, driver’s front. The only special  info I found was a reference to a VW recommendation (which I’ve not independently verified since I lack a shop manual) to bleed 2 cups fluid at each wheel, which may be more than most generic shops would waste :-/ Waiting to hear back from the shop & hoping to get on the road :-)

I use a pinch clamp on all flex hoses to see if that improves the pedal feel; if so, remove one at a time to isolate the problem wheel area. works on any vehicle.

I believe there might be a pressure regulator or something like that inline which requires some special treatment when bleeding breaks. Happened on my 95 EVC.?

?Shop just installed new rotors and front rotors and pads on our 1997 EVC "Vanpira" & now the pedal is spongy and brakes weak. Can't get a panic stop, can't get ABS to activate except on test run on loose dirt/sand road, & then only very briefly on all 4. Classic air in lines, right? so returned to shop & they re-bled using pressure bleed, report no difference & are blaming pads. Pads/rotors were a "set" from Europarts-SD, & Steve there said pads were OEM semi-metalic. Anyone have similar issues with Euorparts SD supplied pads? I still think it's an air-bleed problem. Need to get back on the road, so any inputs appreciated! Thanks EV buddies!? Peter L, Yosemite Area CA.

Thanks Jonathan-The fact that even though only the front brakes were worked on, both front AND rear brakes are now no longer working right really points me toward air in the lines in spite of the shop having pressure-bled them. Saw a VW spec quoted in a related thread that 0.4-0.5 liters of fluid should be bled at each wheel (about 2 cups of fluid per wheel) & I shared that info with the shop.

Have not heard back today :-/ Need to head up to Oregon Sunday, so the clock is ticking!

Re: Front pads & rotors replaced- spongy weak brakes in 97 evc #evcrepair

Air in the line could cause a mushy pedal, another cause is that something is not quite aligned, like for instance a pad is tipping over slightly, or one piston is slow and so the rotor is bending slightly. That might be the issue - I assume your mechanic checked all that - or it might just be that they need to bed in.

Hi Jonathan- Just the 2 front rotors and all 4 front pads. Brakes were all fine, then passengers caliper slider pin(s) stuck and the pad/rotor got chewed up- so the front pads & rotors were replaced.
