Here are the numbers. Hello , the information EPC gives about the pistons is wrong, inside and outside pistons are the same pistons with the part number of the inside piston, the outside-number is a spezial piston which you don't need. see the pictures on my website http://hehlhans.de/280ge/bilder/bremse/topf2.jpg and http://hehlhans.de/280ge/bilder/bremse/topf3.jpg You will find many photos at http://www.hehlhans.de/tipp98.htm about my restauration of the 280GE, sorry the website is in German . @Barm nice, that you know my website. I found your articles about the WUR of the 280GE, I rebuild one 280GE 1984 for the transylvania-trophy 2009 at Deva, Romania http://www.transilvania-trophy.com Can I use your picture of the whole system WUR on my website? If you speek German , please you can write me an email to webmaster@hanshehl.de Sorry, my English is not good Greetings Hans Hehl Edited by Oldtimer 12/19/2008 2:12 AM | ||

When I did this job, I was careful to keep the inner/outer orientation correct upon re-install....... but when I had everything apart, I noticed NO DIFFERENCE between the inner and outer pistons!! Thanks for clearing this up in my mind. Now the question: Why IS there a special outer piston?? Edited by G-AMG 12/19/2008 9:19 AM | ||

Yes, it's good to know that all around the world there are friends of the "Mercedes Gelaendewagen". I'm sad, that my website is not in English. Klaus Hold (http://www.gwagen.de) had translated some time ago several pages of my website, he speeks very good English and his website is also in English. But it is too much work to translate all my jobs about my three G's and my "green baby", my SL55AMG of 2002. But I shot many pictures which needs no translation Dave Gomes (hipine here in the forum) is a friend of mine and visited me in 2005. so long Hans | ||

Edited by G-AMG 12/18/2008 3:19 PM Hello G-AMG, I asked this a specialist from Mercedes and he asked some other folks and searched in the Mercedes archives, but nobody there knows the function of the special outer piston. Only one had the idea, that is a noise reduction of the brake, perhaps. But i will find it out. Hans | ||

You helped me with clearing up a petrol tank fuel level problem (loose hose) a while ago and your website has been a source of help and inspiration to a lot of people (especially that bit about installing 2 windshield washer nozzles on olders Gs). | ||

Hello Bram,
For future reference, the seal rings for the brake fluid passages inside the caliper are p/n A 000 423 1560. The seals are 10mm OD X 6mm ID X 2mm height. MB does not recommend splitting the calipers on the G, but we all know that it can be safely and effectively done. MB does allow the UNIMOG calipers to be split open, therefore, we keep dozens of these small rings in stock for the UNIMOG folks, and the EPC actually shows these rings along with the UNIMOG calipers. http://www.eurotruck-importers.com/index.php?main_page=product_info&cPath=1_73&products_id=944 Now please, no more Suzuki parts on your G. Hope this help,
-Sean P.
Anyone know if the ATE caliper uses the same internal O ring as the Perrot Caliper? No part number is listed for ATE pistons - anyone know the part no for that ? Peter | ||

460332 Date registered: Apr 2006 Location: Europe Vehicle(s): | Re: Photo DIY- Front Caliper Rebuild- W460 Perrot AFAIK the only difference between the ATE and Perrot calipers are the dust seals, the pistons are the same! The Perrot (french) calipers are made to Mercedes specifications, i.e the enginnering around this seal should be the same. For the 460 comes the ATE calipers comes in dual circuit and the later singel circuit, I don't think Perrot calipers followed the Gw's this late. | ||

Razon Date registered: Jul 2008 Location: Vancouver, BC Vehicle(s): 1986 280ge Cabrio, 617A, 5sp manual | Re: Photo DIY- Front Caliper Rebuild- W460 Perrot When I bought my truck, it came with a set of new pistons, and seal kits ...ready to install. I have perrot brakes, but it turns out the kit must of been for ATE since not everything fit. Here's what I observed when I tried to install them The pistons looked very similar...small difference in the area where the dust seal goes on. But they went in , no problem, so I'm using them. The dust seals are different. The ATE ones must have a slightly larger diameter, because they were loose when I tried to install them on my calipers. The ATE O rings have a perfectly rectangular profile/cross section. When I tried to install them in my Perrot calipers, it was quite hard to push the pistons back in (small parts of rubber also broke off of them) It didn't feel right, so I bought the original Perrot dust seals and O ring kits. The O ring profile on the Perrot O rings is not rectangular, the inside corners are nicely beveled. With these O rings installed, the pistons went back in with very little effort. The Perrot dust seals also went in nice, they just didn't like the fact that there was new paint on the calipers. I had to scrape the paint off before pressing them in place. | ||

Many photos I have seen of new replacements are just painted metal there. Any one know if this matters, and should there be an additional layer there to protect or insulate the piston head surfaces?
