I like the adapters made by epytec in Germany. Although difficult to get in the US. They have a variety of brake kits using VAG components. Well engineered and tuv approved. I use their rear brake set up. Matches will with my 4 piston jag front brakes.

It would be nice to know what the difference in uprights is. I know in production the outer wheel bearing changed dimensions, but I remember reading where someone was able to mix and match in the correct order. The other problem might be the caliper bolt spacing. It would be nice to have this piece of information.

We recently had a Syncro with G60 2 piston calipers and vented rotors. The calipers were attached with long bolts spacers and nuts. Pain to take on and off. Rotors were off the shelf Audi 200 I believe.

We just finished another late model vanagon with G57 single piston calipers. These calipers took no spacers or nuts. The caliper bolts fit through the spindle and threaded into the caliper. As far as I could tell, nothing was modified. So the G57 was a cleaner install, but minus the extra clamping force.

Ironically, our 82 stock brakes are dual piston calipers, but on each side of the disc. So, technically in stock form to me is a preferable design. Floating calipers work fine, but just not a fan of them.

The Wilwood caliper in the Boxeer kit is likely a 4 piston caliper. Wilwood lets you choose your piston diameter, which might come in handy with a stock vanagon 23mm master cylinder.

I have no experience with this kit. For the van we had in here, we were able to still buy new rotors and pads from regular vendors. Thats a plus.


That did intrigue me about the hubs - however on the 'big brake kit' page it says
"• 1980-85 vehicles require spindles and caliper bolts from a 1986-91 Vanagon to fit this brake kit. [Part numbers: 251-407-311AH/AQ, 251-407-312AH/AQ]"

From what I can tell, its the caliper adapters and the rotor "hats" that are unique to the Boxeer brake kit. Those items should last forever.

Caliper availability and rebuild kits would not be an issue. You'd have a lot of pad compound options with the Wilwood calipers. Coleman Machine could easily supply new discs. They could even be directional vents. So, when they are available I would not be afraid to pull the trigger on them if I wanted larger vented brakes. No affiliation.

We have the Small Car kit on our 87 with the BMW booster. The brakes are very good and all of the parts are off the shelf at any auto parts store (except the hubs).
The Boxxeer kit looks amazing but I would be worried about replacement parts down the road.

The first step is modified bearing housings. You can modify a set of original vanagon discs by machining them or it looks like GW has bearing housings already.

Quote:
This hub kit is required to install the GoWesty Bigger Brakes kit on any 2WD Vanagon.


Boxeer is also listing a big brake kit for early 2wd vanagons.

Members have been cobbling bigger brakes on vanagons for quite a while. Some folks are more interested in a complete solution that doesn't require crawling around junk yards. I can't believe how the supply of late model uprights have dried up. Crazy.

Looks like you still need the later model spindles thru small car

"Please note: This kit will fit an 80 to 85 Vanagon if you install front uprights (spindles) and wheel bearings from an 1986-1991 Van."

We just had a van in here with was likely a Van Cafe big brake kit based on Audi discs and calipers. I do not see a complete big brake kit on their website any longer only replacement parts. It's not really clear.

Before I put Smallcar brakes on my Syncro, I actually did not like my wife to drive it. She is accustomed to a modern car that will actually stop in an emergency, and the Syncro required that you knew in advance that you would have to push on the pedal "as hard as you possibly could" to lock the wheels.

I started down this path of 'brakes', and in doing so, heeded the advice of a mechanic who put it succinctly as; "Why don't you go test it? That's what I will do if you want to pay me". So I went out to a stretch of reasonably new, grippy asphalt and did some panic stops, and found it **was** actually possible to lock the Syncros wheels some of the time. I was pressing so had on the brake pedal that I thought I might 'break' the pedal. This is not safe. Certainly my wife would not do so, after getting out of her 'modern' car. No one would. This notion would be revisited sometime, if any, AFTER the impact.

So I respectfully disagree on a couple points of our friend Dogpilot, who always offers great help on this forum! I think emergency situations should be the largest part of a brake component decision.

All that is necessary is the impetus to go test it. Not everyone will do this. My wife would NEVER test a panic stop,,,,,, she just would not ever do it, simple as that. I even felt a little silly, skidding a Westy.....

All that is needed is a safe place to do it, take all the stuff off your shelves if you have a Westy Wink and slam on the brakes. Then you can stop typing and start deciding. My decision was easy, after 5 minutes of testing, my car was not safe. And with the new Audi brakes, (smallcar) I felt so much better, almost like driving a new car, I can chirp the wheels anytime I want to confirm that I have max stopping power anytime.

I am fine with the smallcar front kit cuz I already own it, but if anyone makes a kit that support the brake lines better you might consider that kit. Here's my story: http://www.thesamba.com/vw/forum/viewtopic.php?p=2354709#2354709 my installation was more difficult because I was using Audi 15" wheels that do NOT have the proper offset. In this thread you can see a photo of the brake line support that you should inquire about.

As for the rears? I had a horrible fright one time backing down a steep hill in my 2wd. The fronts were skidding, of course, backs were doing all they could, which was basically "nothing". So I bought the rear disc kit too for my syncro (but have not installed it yet.....).

Hey Eric,

When are you gonna make some of those for Syncros?? I just finished a set of the Audi Turbo caliper carriers (ala Syncro.ca), but I really want Porsche pattern.

Yes, the "E" in E-Brake stands for "Emergency" its very handy in Florida when your aftermarket master cylindar fails....which is every 6 months for me LOL......Maybe rear disc brakes would be a better mod for us Floridians, apparently the rear drums only account for %40 of total braking. But having larger/better rear wheel disc brakes and stock front discs is probably dangerous unless you are Rally racing.

and you are very correct, my Sirius Satelite is a must have in Florida traffic, also a hands free wireless cell earpiece helps too. Wink

When purchasing wheels, some wheels with the wrong ET might not clear the new kit. Most should. But check it.

HUH?? OK - pardon the lack of knowledge here, but just how is one supposed to "check it out" - what do you measure on your wheels to determine if it is possible or not?
J


I meant: Do some research especially here. Most combination have been tried already. Having an offset too extreme is very likely to bring some clearance issues with the brakes. If you go 16', and plan to go with big brake kit afterward. You may stick to known/conservative ET.

Option #3, my kit. Porsche 993TT calipers, rotors. (big reds).

I replace the entire hub assy with mine. The bolt pattern is changed to Porsche 5x130mm. Min wheel size = 17" et 50

I have 2 kits in stock.

The subject of what wheels fit the brakes can be tricky. Some wheels may have the correct ET, but then, in the case of steel wheels, the welds can interfere on the inside flange with some of the brakes. You kind have have to do a trial fit.

Huge difference? Do you live on Pikes Peak? Just kidding Laughing i have no doubts about gaining brake performance in the mountains or towing but im not sure just how much improvement id see over 86'-91' brakes down here in flat-land-Florida. Id really like to see MotorTrend TV-show style brake test say 70-0 MPH on YouTube......untill someone does a before and after test this way, im driving slow and keeping that gap between me and the car in front......or maybe ill do the upgrade if i find both an Audi and 86' Vanagon next to eachother, at the junk yard Wink Anyone have any actual test data for el cheapo's like me? Maybe i should start another thread....sorry!
