OllieVR6 0 Posted August 8, 2011 I'm just wondering what the benefit of the mk4 rear brake upgrade is? I see a lot of people do it, but aren't the disc and pad sizes the same? Or do you get more surface contact? Quote Share this post Link to post Share on other sites
OSV 0 Posted August 8, 2011 Mk4 calliper upgrade provides more reliable handbrake less prone to seizure Quote Share this post Link to post Share on other sites
OllieVR6 0 Posted August 8, 2011 Ok. Is that something to worry about on a car used regularly? I mean it's not at the moment, but it will be once it's MOT'd and I actually prefer the look of the standard callipers to the mk4 versions. Quote Share this post Link to post Share on other sites
OSV 0 Posted August 8, 2011 no not until they seize or play up, then its just a question of do you fit the same again or a trouble free upgrade Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted August 8, 2011 The MK4 calipers benefit from a revised handbrake mechanism which is less prone to jamming on. Unfortunately the squawking noises in reverse and freezing up in the winter issues remain. It's not a brilliant caliper design by any means, cheap and cheerful, and there are no alternatives in the aftermarket in Corrado fitment, so we are stuck with them.

aide 0 Posted August 8, 2011 the rear calipers on my first 16v seized on in spite of daily use, not just an issue for the weekend warriors. Quote Share this post Link to post Share on other sites
boost monkey 0 Posted August 9, 2011 I think the mk4 rears are better as they are aluminium alloy and not iron, so they won't rust. Quote Share this post Link to post Share on other sites
Ralphead 0 Posted August 9, 2011 Far lighter too. Quote Share this post Link to post Share on other sites
Critical_Mass 10 Posted August 15, 2011 Any particular spec mk4 or any? Quote Share this post Link to post Share on other sites
Jim Bowen 1 Posted August 15, 2011 when i went to the dealers for the calipers he came up with 9 different part numbers for them, all with a different letter at the end, i just went for the latest letter Quote Share this post Link to post Share on other sites
Critical_Mass 10 Posted August 15, 2011 (edited) So are they the same calipers on every model. Im thinking i'll need 2.0 GTi calipers, but im not 100% sure exactly what model to get them off. Whats the part number mate, do you have it to hand? Also what thickness pads did you use 15.2mm or 17mm? How much were they for the pair?

poll250 0 Posted August 16, 2011 I use the 17mm VR pads on my mk4 rears with no problems. The only difference that I know of between different mk4 callipers is that the slot the handbrake cable goes into is wider on some, as i think some mk4s had a different size end to the cable. The pair I bought had this wider slot, but I just used some mole grips to close the gap and it's been fine for 18 months. Quote Share this post Link to post Share on other sites
dragon green 5 Posted August 16, 2011 I bought these ones of e-bay about two years ago, direct fit, http://www.ebay.co.uk/itm/NEW-REAR-BRAKE-CALIPERS-VW-GOLF-MK4-MK3-MK2-CORRADO-/350479569093?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item519a35d0c5 Quote Share this post Link to post Share on other sites
Critical_Mass 10 Posted August 16, 2011 Cheers chaps. So bar the difference in the gap for the handbrake cable, they're the same on all models. Do i need mk4 handbrake cables too? Quote Share this post Link to post Share on other sites
dragon green 5 Posted August 16, 2011 I used Corrado cables , i replaced mine with new,when I put the calipers on. Quote Share this post Link to post Share on other sites
Dox 23 Posted August 16, 2011 I suppose what really matters is the overall pad / disc / pad measurement. I've got a pair of calipers off a 1999 Golf V5 estate in the shed, if you want pics or measurements shout up. Quote Share this post Link to post Share on other sites
harryc 0 Posted August 16, 2011 I used corrado cables, mk4 rear callipers (from a bora), rado discs (rado bearings etc etc) and mk4 pads. No clearance issues. I have a set of mk4 rear callipers for sale if you want them, just pm me an offer. Quote Share this post Link to post Share on other sites
