STRBramley Posted May 28, 2014 Share Posted May 28, 2014 Hi all, I picked up my 350z last weekend and I've noticed a grinding noise that seems to occur at very low speeds and its much louder when braking. The discs seem fine on all sides apart from the rear o/s which looks very uneven. There is also alot of brake dust/rust on the alloy which I assume is from the disc? Does anyone know what could cause this? Could it be because it hasn't been driven for 6 months? Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted May 28, 2014 Share Posted May 28, 2014 Best to remove all wheels and pull the pads for inspection. The rotor in your image is shot, I would hate to think what the condition of the inside face of the rotors are like. Alex. Quote Link to comment Share on other sites More sharing options...
Kraziekatz1 Posted May 28, 2014 Share Posted May 28, 2014 Corrosion on brake discs is common but the developing rust is usually removed by the pads under braking. If it's been stationary for a while, check your discs & pads. Quote Link to comment Share on other sites More sharing options...

MITZ@CougarStore Posted May 28, 2014 Share Posted May 28, 2014 Best to remove the wheel, inspect the discs and pads, the grinding noise could well be the pads worn down to the metal and eating into the discs... Quote Link to comment Share on other sites More sharing options...

How easy are they to replace on the zed? And what's the cost of a pair of rear pads? Quote Link to comment Share on other sites More sharing options...

Am I causing any additional damage to the car other than wearing on the disc and pad while I wait to get them sorted? Quote Link to comment Share on other sites More sharing options...
MITZ@CougarStore Posted May 28, 2014 Share Posted May 28, 2014 Is it the rears that are grinding, what's fitted on the front, if it's standard discs on the front I'd emulate the same with the rear, it also looks like you have Yellowstuff pads fitted too, which we also supply... First port of call would be to inspect both front and rear pads and discs and then see which is needed... Quote Link to comment Share on other sites More sharing options...
Marcus01 Posted May 28, 2014 Share Posted May 28, 2014 Looking at your pictures I would very much doubt you have any pad at all, looks to me like the pad backplate is running on the disc. Do not drive until its sorted, IMHO. Quote Link to comment Share on other sites More sharing options...

I'm pretty certain the grinding is coming from the rear and all the other discs look smooth so I'm guessing it's just that one. I'll take a look at the front discs and pads in the morning to see what I have on there. If it is the Yellowstuff pads I need then will this combination work? Discs - Are the OEM? I'd like to keep it as close to OEM as possible. http://cougarstore.co.uk/index.php?main_page=product_info&cPath=1_7_4&products_id=40 Pads - http://cougarstore.co.uk/index.php?main_page=product_info&cPath=1_7_5&products_id=44 Quote Link to comment Share on other sites More sharing options...
MITZ@CougarStore Posted May 28, 2014 Share Posted May 28, 2014 You can indeed go with the combo you've linked, as the discs will be standard and it'll mean you'll be using the same pads that are already fitted... Quote Link to comment Share on other sites More sharing options...
MITZ@CougarStore Posted May 28, 2014 Share Posted May 28, 2014 Also, make sure you inspect the inside face if the discs too, as you can visually inspect the outside but check what's happening on the inside too... Quote Link to comment Share on other sites More sharing options...

Excellent, thanks for your help. I'll check what I have fitted to the front in the morning and report back. Would I have to take the alloys off to see what pads are fitted?

MITZ@CougarStore Posted May 28, 2014 Share Posted May 28, 2014 With the JDM calipers you can see what's fitted but to get a proper look at the discs and pads I'd remove the wheels... Quote Link to comment Share on other sites More sharing options...
gsexr Posted May 28, 2014 Share Posted May 28, 2014 Do yourself a favor mate and get someone who knows what there doing to look at it. By the questions your asking this is gonna go wrong.

I had a quick look this morning but I've not had time to remove the wheels. I know it isn't much to go on but can you tell what front pads I might have fitted from these pictures? I'd like to get them ordered asap. Quote Link to comment Share on other sites More sharing options...

MITZ@CougarStore Posted May 29, 2014 Share Posted May 29, 2014 No set guide for how often they need replacing as it comes down to driving styles, motorway use or daily drive etc... Quote Link to comment Share on other sites More sharing options...

Is it possible they have never been replaced? Would I be better buying new discs and pads all round to match? Quote Link to comment Share on other sites More sharing options...
MITZ@CougarStore Posted May 29, 2014 Share Posted May 29, 2014 If you needed to replace the full set then I'd keep it matching all round, the link you posted yesterday come as a front and rear option too... Quote Link to comment Share on other sites More sharing options...
