R33 Rear Caliper Problems?

[siddr20]

Hey everyone..

Just out of know where (and i mean out of know where) driving along to the petrol pump(1km from my house), the car started to squeak/squeal and make weird noises..

Im getting scared here.. thinking somethings stuck under the car..

pull over, nothing there.. Start driving again and the noise gets louder and louder.. Pretty damn loud..

Anyways long story cut short.

Me and my friend pin pointed the noise to the rear driver side caliper area.

Yesterday we pulled out the brake pads, cleaned the rotors plus claipers with nulon brake spray..

Put everything back together and no noise.. Drives like a charm and brakes like a charm!!

Then this afternoon driving along it did the same thing (however a lot less noise, but you can hear it squeal again)

So what you guys think could be the problem?

Is it the piston in the calipers not engaging or something??

Brake pads have probably 30-40% meat left..

BUT the noise only comes from that side(driver)

Any suggestions before i go to a brake shop??

Cheers all

im assuming it only happens when you apply the brake pedal?

[siddr20]

Nope thats the funny thing..

the first day it happened.. i reversed a little and the noise was substanially louder than driving forward...

[gtrchick]

could possible be the backing plate rubbing against the rotor, a rock stuck in the caliper or rotor area, or a wheel wieght if you have mags.

how does braking feel?

could be a piston? notice you have a series 2 - so it's not as old as some other skylines, but these cars are 10years+ old

Well we took the brake pads out.. sprayed the shit out of calipers n everything inside.. lots off dust pouring out.. so its pretty much clean now..

But the noise went away..

But then a day later (today) i heard it again (not as loud as the first day it happened)

(drove this morning for atleast 50kms, with no noise!! Then in the afternoon, i heard it again)

Yup i have a series 2

But its only coming from the driver side!!

Brakes feel normal!! they work and pull up quite well..

It sounds like as if a sharp object is touching the rotors (like sharp nails on a glass)

hmm id be inclined to say the indicator would be touching the rotor to say you pad is low, but you've already checked how much meat is on the pads. Are your rotors glazed? because it could be just the rotors are glazed with a smooth pad making a squealing noise, just take the pads out and scuff them up on concrete, and get some emery paper on your rotor, if that makes any difference, as its pretty cheap to do that, then maybe consider getting your rotors machined, or get one of those air biffer/grinder things on it, they come with little scuff pads and you can take the shinyness off the rotor.

gtrchick- i have a feeling the rotors are glazed and need replacing.. The surface isnt that rough to be honest..

Or the piston inside is getting stuck somehow?

i will try and get it checked out..

but the weird thing is, that the noise is only coming from the driver side!!

Worst comes to worst, i will replace everything (ohh god im gonna be broke then lol)

thanks for the help!!

Any other suggestions?

OHh also..

my rear driver side shock is leaking as well..

Why is it only the driver side?

Could it be the oil leaking into the caliper area??

I think maybe thats it??
