Update 23-01-2010: I bought some VW passat calipers which included the brackets I needed. The calipers themself look a lot like the golf calipers, but the handbrake lever is different and the brakeline attaches somewhere else.
Here I test-fitted the passat calipers on the car:
As you can see, the calipers are way to close to the exhaust! In the picture it looks like it just fits, but the caliper isn’t in it’s widest setting yet. If the brake pads would be really worn, the caliper will touch the muffler.
So, I have to change my exhaust… 🙁 Well, I always had the idea to replace the exhaust with a super silent one (this motorcycle exhaust isn’t loud, but it isn’t silent either). So, now I am looking for a different muffler.
Caliper Bracket Differences
On this picture you can see the two different caliper brackets:
They look the same from this angle.
But in this side-view you can see why I need the Passat brackets:
The Golf bracket is angled, this brings the caliper outwards. The Passat bracket is straight, which is more convenient for the VW beetle rear axle and Porsche 914 disk combination.
Here you see the part number of the passat bracket:
It reads: 5780/2 Lucas. According to the add, they are for a Passat 3b from 1997 and onwards. This means they come from a (Dutch) Passat B5, according to this Wikpedia page.
The Golf IV caliper fits without problems on the Passat 3b bracket:
In this picture I allready removed the muffler, so plenty of space now.. 🙂
I also de-rusted the second hand Golf IV calliper and the bracket, they still need paint..
Update 13-02-2010: My neighbour machined the other drum too, so I could test fit the left side:
It, again, fits perfectly! 🙂
I really like the website. Very informative. Great work on the car. My question is about the calipers. What year golf did they come from or are they all the same.
Hi Heath,
I don’t know for which year they are. I just searched for rear brake calipers for a VW Golf IV.
I assumed they were all the same… but I am not sure if they are.

Hey Gerrelt,
Thanks for the reply. I ended up going with 08 beetle calipers. They fit on the empi brackets perfectly. I would like to change the brackets to something with the same 0 offset as the empi brackets so I could buy the pads at the local parts store. Maybe Passat. Not sure. The 08 beetle calipers are much better than the empi calipers. The empis were thin and were flexing which caused the outer pad to not make up fully with the disc and was causing much noise and vibration. Next i’m going to add wildwood calipers to the front. I have the brackets orderd now. I’ll have a video up on youtube soon on the brake conversion. Ringo774. Thanks for the reply. Later
Yeah, I’ve read that before, the empi calipers aren’t very good apparently.
And that’s the exact reason I used the Golf calipers too. Now I can get brakepads from the local parts store.
I will check out your youtube channel!
Great and good job
Many thanks for your information and full details supported with pictures.
god save you.
Thank you for the kind words!
Hello Gerrelt,
Thanks for this site, it is very useful. After reading it, I am doing the same rear disc brake conversion. I have one question: the Passat caliper brackets are from what YEAR of Passat? I ask because in the US, the Passat B3 was from 1988-1996, but I believe in Europe they used “Typ 3B” for 1998-2006. So it is very confusing: 3B or B3. If you know the year of the Passat the brackets came off, that would help me greatly. Thanks! -Matt in Virginia
Hi Matt,
I checked my e-mails, and they guy I bought them from described them as being for a Passat 3B from 1997 and onwards.
If I check this on the wiki page for the Passat it must be a Passat B5, which also is (confusing, indeed!) described as type “3B”.
See this page:
https://en.wikipedia.org/wiki/Volkswagen_Passat#B5_and_B5.5_(Typ_3B_and_3BG;_1998%E2%80%932006)
Apparently it was launched in 1996 in Europe and in 1998 in America.
So, I you look for a 1998 to 2006 Passat, you should find the right caliper brackets.
I will update the site with this info.
Greetings,
Gerrelt.
Perfect, thank you. I was working from the same (confusing) Wikipedia page. May I ask, how do you like the brake performance with this setup? And what brakes do you have in the front? My plan is to put Wilwood 4-piston calipers in front. My pedal assembly has separate master cylinders for front and rear,so I should be able to balance the front/rear brake bias by sizing the master cylinders correctly. -Matt
I really like this setup. I’ve got a firm pedal and good braking performance.
In the front I have the standard VW beetle disk brakes and calipers, and I am using a standard (19mm, if I remember correctly) super beetle master cylinder.
Hi,
I own a VW 1600 beetle and plan on upgrading the rear brakes to discs. The difference is that it uses a 5 hole hub instead of 4. Any ideas as to what brake disc would suit it? Thanks in advance
Which 5 holel hub do you have? Is it the standard VW 5×205 pattern, or the Porsche 5×130 pattern?
If you have the last one, you could try the 914-6 rear disk brakes. The 6 cylinder model of the 914 used a 5 lug pattern.
If you have the first one, the VW one, then I don’t know. I believe they do sell drum brakes with Porsche pattern. You could use those to have them machined into hubs.
In both cases, I don’t know what effect it has on the spacing for the caliper. I don’t know if the offset for the disk will be different then my situation.
Maybe you could aks Sharpbuilt?
Hi, I love your work on the rear brakes using golf parts, I’ll be doing the same. I’m wondering do I have to use the Australian shark caliper carriers or is there an English crowd selling them, thanks in advance

Hi Broz,
Thank you for the kind words!
Sorry, I don’t now of any UK compagnies selling these adapters.
