Woppum Posted August 2, 2005 Report Share Posted August 2, 2005 Right the brakes are attached souly by the wheel, not by a bolt connecting it to the axle. ? The problem as I see it is, when teh pads begin to wear, the brakes will become looser as they will take up less space, this could casue problems with rattling, or even getting stuck in the wheel!!! Gecko or anyone else with porsche pads how are your fitted? Link to comment Share on other sites More sharing options...
Mook Posted August 2, 2005 Report Share Posted August 2, 2005 Which upgrade kit have you got fitted? This shouldn't be a problem - the caliper is attached to the wheel hub via a mounting bracket. There may be an extention bracket which was supplied with the kit, as with the ECS Tuning Stage 5 upgrade if you run 358mm disks as I do. The calipers stay in exactly the same place - the caliper pistons move in as the pads wear. Technically they work no differently to the stock brakes on any car.

Woppum Posted August 2, 2005 Author Report Share Posted August 2, 2005 If you take yor wheel off, are the porsche brakes secured totaly in place, or are loose to flop about? Mine flop as are attached to the wheel, and was told as the brakes wear down they will become looser. AmD were out but I will check with them tomorrow. They are 993 Turbo pads and discs Link to comment Share on other sites More sharing options...
Mook Posted August 2, 2005 Report Share Posted August 2, 2005 I think someone has been telling your porkies... Apologies if I'm teaching egg sucking routines here! This first pic shows the brake caliper - it happens to be the Cayenne Turbo caliper that comes with the ECS Tuning Stage 5 conversion, but you can see that the bolts go through the caliper. As you can see, it is a solid cast item. The pads "float" in place, being held just onto the disks by the pistons in the calipers, with the edges of the pad being secured against the back of the caliper: A photo from underneath my car (yes, I know it's filthy and some of the blue paint's coming off - but they stop the car no problem!): Hopefully you can see from the pic that the visible bolt secures the caliper to the hub, which is attached to the subframe via the lower link arm and the ball joint. The other securing bolt is not visible (but it's there!). The top of the hub is connected to the suspension strut. There is no physical way that the caliper would be just attached to the brake disk. If it is on your car, then you need to stop driving it now Hope this helps, but if not, post again and I'll try to dig out some more pics and annotate them. Will take a photo of the Cayenne Turbo pads going onto my R tomorrow so you can see how they are held in place in the caliper. HTH Link to comment Share on other sites More sharing options...
Dan32 Posted August 2, 2005 Report Share Posted August 2, 2005 If they are attached to the wheel, surely they will spin around with the wheel and not actually stop the car whatsoever. Are we talking about the right part here? I know on motorbikes you can have a 'floating' disk which has loose connections to the main rotor and makes a racket as you ride up the road. Its a racing thing and I can't remember why they do it. Can you get floating disks for cars? Might also be semi floating. Link to comment Share on other sites More sharing options...
Mook Posted August 2, 2005 Report Share Posted August 2, 2005 [ QUOTE ] Can you get floating disks for cars? Might also be semi floating. [/ QUOTE ] Yes, that's exactly what the ECS Tuning brakes are, but they use a clever technique which allows the disk to expand with the heat but not clatter like a bag of bricks at low speed.

FiftyPence Posted August 2, 2005 Report Share Posted August 2, 2005 I do hope we are misunderstanding Wopps here, surely he doesnt truly believe that a brake caliper just goes over the brake pad and 'rests' there without being fixed by the bolts to the hub bracket Link to comment Share on other sites More sharing options...
Woppum Posted August 3, 2005 Author Report Share Posted August 3, 2005 Yes I would be suprised. All I know is what I was told by the ATS guy. I have to do a big trip today so they have to be checked out. God not again!!!! Link to comment Share on other sites More sharing options...
Woppum Posted August 3, 2005 Author Report Share Posted August 3, 2005 Right I have just checked with AmD and they say that bold, is simply a locating pin, and does not actually hold the brakes in pace. I was told its only about 8mm and does not have the strength to hold the brakes in place. In fact as the brakes are not designed for that car, having that pin in can actually warp the brakes. But that explains it as the brakes will sagg when the wheels are taken off. So just to confirm. it is the wheels that hold the brakes on! Link to comment Share on other sites More sharing options...
Mook Posted August 3, 2005 Report Share Posted August 3, 2005 OK, so now I get what you're talking about. There is a locating pin which sits across the middle of the caliper, as in this pic (it's a bit bigger on the Cayenne Turbo calipers, but is there as a locating guide. The pads can't physically "pop out", because, looking at them in this pic, they are longer at the top and bottom than the gap in the caliper: This is a pic of the calipers fitted and bolted up from the back - there is definitely no wheel on and you would not be able to physically move the calipers without unbolting them: Wopps, I can categorically and utterly confirm that the wheels do not hold the brakes on. I'm not going to get into a p*ssing contest about whether they do or don't, but please trust me on this. I don't often admit this, but I was a VW engineer for four years before going down the evil route of setting up in business in the software industry Link to comment Share on other sites More sharing options...
Woppum Posted August 3, 2005 Author Report Share Posted August 3, 2005 Well I am very confused now. The brakes seem fine and don't move around one bit inside the wheel. If something was wrong I would know right? Ive just about had enough. First the exploding cat, then new exhaust, then new sat nav, then new CD player, then new rear diff, then a puncture, then 4 new tyres then a fright with the brakes. And all in the last few fecking weeks. I think apart from Smudges original lemon, I could be having the most bad luck with this car. I just can’t be bothered, I just want to drive it and enjoy it, so the brakes will have to wait! Link to comment Share on other sites More sharing options...
mooret Posted August 5, 2005 Report Share Posted August 5, 2005 Woppum, did you say you were told this by a tyre fitter (ATS)? QED! Link to comment Share on other sites More sharing options...
