Knocking Noise

[vc123]

Hello all.

So, I've just had my brakepads changed and rotors replaced. The guys that did it work next door to me and will look at it for me on Monday, but seeing as I need my car over the weekend I wonder if anyone would have any idea what is making this knocking noise. Now I know 1 of my rear coilovers has a leak and is knocking but this is a totally different sound and a seperate issue (i think).

When I accelerate I would not hear this knocking but as my foot is off the accelerator I hear a series of knocking noises kind of like how if you would drop a snooker ball onto a table. It seems to be knocking as the wheel spins (from the sounds of it). Any idea what it may be?

The higher the speed I'm going at the louder the knocking is. Reason I ask is simple as I need to use my car over the weekend. Will definately take it back on monday to have it looked at but if it is something simple I may take a crack at it tomorrow morning.

Thanks in advance for any advice that is given.

Possibly your brake calipers hitting your rims? If you replaced your rotors and pads then it would have pushed the calipers further out by a tiny bit, maybe they are now hitting your wheels?

don't think they are actually hitting the stock rims on the GTR. Have 25mm spacers all around (came with car to make it look more aggresive)

Our skyline brakes don't work like that, the Stagea however, does work like that (it's a sliding caliper set up with pistons only on one side I believe).

My guess is something isn't done up properly

Have you gone over all the bolts??

I would say something is loose down there

Yeah I'm about to jack it up and get under there to have a look.

Thanks for the commenting guys.

I'd be checking to see if the spacer nuts are done up!

My 33GTR is experincing exactly what you described too. I posted the question in SA (http://www.skylinesaustralia.com/forums/Rear-Knocking-Noise-t294230.html&pid=4910119) but I havent been able to work it out yet.

Would love to know the answer and fix it...

wheel nuts loose!!

Alright, after a whole day of running around doing errands and tryign to figure out the problem with my car, I've just realized that 1 of the spacers was not bolted back properly (loose) (Thanks R31 POWER)

Now just need to find my damn allen key for my wheel nuts to get it off and tighten it all up.

Cheers for the help guys.
