Rear Disk Brakes

Update 27-12-2009: Yesterday I gave a drum and disc to my neigbour, and today he gave it back to me.

A nice before and after picture:

 

My neighbour made it quite a bit lighter! 🙂 I think it looks great!

He machined them so the disc would fit nicely over the drum. And he machined 2 mm off the surface, leaving a 2 mm rim in the middle that fits the inside hole of the disc perfectly.

Of course I test fitted it:

 

With the disc on:

 

I am very happy with it! It fits great!

I still need two M6 bolts to hold the disc to the machined drum.

These will only hold the disc so it won’t fall of when you put the wheel on. The wheel bolts will really hold the disc in place.

Now, the other drum has to be machined too.

  1. 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.

      Greetings,

  2. 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!

  3. 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

  4. 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.
