Extreme Rear Brake Rattles

[kymbo]

Picked up my new Black R35 GTR 4 weeks ago. There is a constant rattle in the back. When I apply the brakes, the noise goes away.

The dealer said it is normal and because the brake pads are undersized so they will not jam when they expand from heat on track days. Therefore they rattle.

They said all new R35 GTR's are the same. Surely not, every time a friend gets in the car they are amazed at how loud the brakes rattle. Makes the car sound and feel cheap. Not a good thing for a car that costs near $200K.

Other than the brakes, I love the car!

DOES ANYBODY KNOW HOW I CAN FIX IT, BECAUSE NISSAN SEEMS TO THINK IT IS OK??????????

IT IS DRIVING ME NUTS!!!!!!!!!!!!

I think it's the pad retainer clips. Is your car 2010 model? One of my friends is getting the HPC to order one from Japan. Check with the HPC first.

Thanks RCCC

It is a 2010 model.

The Nissan guy told me they come with a retainer clip standard?

Who or what is the HPC?

Also, does anybody else suffer this problem?

Many thanks!

rear pad rattle is "normal" however i would never call it "extreme". Just the odd clunk/clank. maybe something else going on if it really is extreme. you could try putting anti-squal (stick-on) shims (rear pads dont have them, whereas fronts do). if you are in sydney i have a bunch of the stick on anti-rattle shims if you want to try those.

Have got Endless MX72 pads on.

They are beaut, and don't crack during trackdays.

No rattles, just the occasional slow speed squeal of race spec brakes.

you'll find as the pad meat gets less and less they cavitate around more

Thanks Guy's!!!!!

With the information you provided, I should be able to get it fixed.

Next!!!!

I am only one week away from my first 2,000K service and have decided that, straight after, I will install the full cat (primary) back 'Willel Racing' Titanium Exhaust system, Cobb access tuner, enlarged cold air tubes kit & filters from the air filter boxes to the engine intake plennum, as well as cold air ram/funnel intakes for cold positive pressure air delivery through to the front of the air filter boxes.

What sort of AWHP gain should I expect to see. Anyone know what sort of 0-100K and 400 mtr gains?

Also, any recommendations or added suggestions on my choices???

Thanks again.

Based on my experience these changes should see yo achieve btw 340 and 360 atw, and a 0-100 of 3.4seconds (from 3.7). Maybe an 11.3 quarter.

Do the dump pipes and intercooler pipes and boost controller and youll see a reliable 370 -380 (I had actuators too). I can do a reliable 3.0 0- 100, and high ten second quarter mile on standard 98 gas.

If you have bigger future plans, go straight for the 4 inch exhaust system. My HKS midpipe and dump pipes are fore sale shortly otherwise.

2009 spec "return springs" will reduce the rattle, they changed the design on the 2010 car and this is a very common complaint, the design change was to stop rear pad squeal (which wasn't an issue) but made the rattle issue worse.

Thanks John D!

My Nissan service guy came up with a good fix. He used a bead of brake sealer Around the pad perimeter and it is now perfect. However next service I will add the 09 retainers!

My dealer also fitted a Willall mid pipe for me, what a difference and u win on all fronts, weight, power and sound!

I am looking forward to my first sprint day at QR to try my car out for the first time.
