Dynamic Turtle Posted March 14, 2012 Share Posted March 14, 2012 OK so I took the car to a garage this morning to have the brakes looked at. They've been squeeling horribly and rubbing at low speed, causing an audible chafing sound. 1) The car had new pads put on it 400 miles ago, but the previous garage has "chamfered the pads heavily in an attempt to reduce squeeking, leaving only 70% of the pad touching the disc". 2) There are no shims on any of the pads (surprise surprise) 3) There is a small lip on the discs, approximately 1.25mm all around Now, obviously the lack of shims appears to be the main culprit here. I've seen many posts where their absence has been blamed on brake squeel. My guess is that it would be most economical to keep the existing pads & discs and simply fit shims. The car still brakes very well with the "70%" contact, so I'm reticent to change pads. However, I've also read that discs should be changed once lips hit 1.6mm. I still think we're several thousand miles away from that, but they will need to be changed at some point. He said that doing two seperate ramps obviously adds labour charges (which seems logical enough), and recommended that I change everything now in one go (surprise surprise). He's quoted me £809 for new ADL pads & discs. My preference simply be to have shims fitted and see how that goes. What are your thoughts?

docwra Posted March 14, 2012 Share Posted March 14, 2012 Use a different garage. Im no Z33 brake expert, Im sure one will be along shortly, but sounds like he's feeding you a load of shyte. I certainly wouldnt go near any company that starts messing with standard brakes to make them stop squeaking, maybe they could correctly diagnose the cause in the first place?

Dynamic Turtle Posted March 14, 2012 Author Share Posted March 14, 2012 I am using a different garage, hence why I took it to a new guy this morning. The previous garage was a porsche specialist, so I assumed they'd know what they were doing. Seems like their experience with Cayennes & 911s doesn't quite apply to Zeds...

Ekona Posted March 14, 2012 Share Posted March 14, 2012 Nah, they're just used to the typical Porsche owner walking in and handing their chequebook over! Get some shims and fit them yourself, it really is a very easy task Quote Link to comment Share on other sites More sharing options...

Ekona Posted March 14, 2012 Share Posted March 14, 2012 10 man points added for admitting that, but 20 man points removed for admitting that ;) Take it to another garage to do in that case, I would. But definitely just shims for now, I'd leave the discs & pads as they are. Quote Link to comment Share on other sites More sharing options...
Dynamic Turtle Posted March 14, 2012 Author Share Posted March 14, 2012 Been speaking to Alex, he said certain combinations are more prone to squeal than others. Discs are Nissan/OEM, pads are Pagid. Quote Link to comment Share on other sites More sharing options...

Its more to do with the fact that I live in an apartment block, with no tools and no space on the road outside to work on the car. Not really practical...

Dynamic Turtle Posted March 14, 2012 Author Share Posted March 14, 2012 OK so I've done a bit more research. Apparently Pagid's are popular on the track and have effective velocity-killing ability, and I can certainly vouch for that. They stop the zed. But they're also known for squealing badly. Apprently this is less of an issue on the track for obvious reasons. Apparently pagid's are common on porsche (probs why the porsche garage used them - had them lying around maybe). Anyway, I'm going to leave the current set of discs on the car and change the pads for standard brembos (with shims from OEM nissan pads). Might as well have fresh pads on the car that haven't been chamfered down. They're not going to break the bank. My bro has offered to change them for me on sunday, in exchange for a milder beating after getting fired last week. Hopefully they'll be a damn sight quieter than the bat-killing pagids. Massive thanks to Alex for his advice and competitively priced gear DT Quote Link to comment Share on other sites More sharing options...

Massive thanks to Alex for his advice and competitively priced gear DT Dont porsches usually use texstar? Yes you do get good pagid pads but most pagids are bought on ebay or motorfactors as they are cheap. They are also just the same if not slightly worse then some oem pads. You would know if you had better pagids on there as you would pay for them Quote Link to comment Share on other sites More sharing options...
