There may also be dust on the pads.

The squeek is usually caused by wear on the disc, usually the center is worn but the edge is not.  Machining the disc when changing pads will take care of the problem.

For a quick fix, say if selling the car, pull the pads and put shoe polish on them. this is a short term fix.

It is a copper compound grease that soaks into the pad and lubricates the disk - be careful not to apply too much - take a 1/2 teaspoonful on the end of your finger and smear a line from the inner hub to the outer edge across both sides of your disc. Taking the wheel off makes it easier, but if you have mags you will be able to do the outer disc fairly easily.

Warning - Do 1 wheel at a time and then ride it till it is hot, to soak into the pad - your braking on that wheel will be poor for the first few pumps, so don't hoon around while your heating it up - also don't burn your fingers off when doing the second wheel - the disc will be very hot. Just be sensible when doing this - maybe leave it a day between front and rear application, starting with the noisiest wheel.....

The problem is that the pads in are too hard - will last long, but less efficient....

Get the grease from a autoshop or tool sales place..

common problem

 put some stop squeak where the piston contacts the pads

can buy it at supercheap,autoone, repco..etc 

i wouldnt be putting any sort of lube near the braking surfaces 

thanks guys for your help, and the idea of the products to purchase, i knew there was some stuff available.

Colin, no issues with fluid, i always make sure thats full 

Now I know how to stop my sqeaking brakes too. Thanks guys.

I agree with Davebarry most likely cause is you got hard pads. I disagree with putting anything on them to make them quiet, as it can be very dangerous. Best solution is to remove your brake pads again and get a hacksaw and cut some criss cross grooves in them (Making diamond patterns) about 3mm deep. This will get rid of your noise. I am qualified mechanic and have encountered this numerous times.

we have 4 here at work - all have periods of squeaks - paticulary when muddy - and the gearboxes are quite noisy - but good reliable vehicles.

Mako,

There is a spray that my dad has at his workshop that you spray. I can ask and get back to you or i can lend you some.

we spray this substance to most cars taht we change brake pads on.

i use to work at his mechanic workshop when i was still at uni.

I would be interested. Spraying something is about the strength of my mechanical skills (Lol).

Yo Mako- you can follow any of the advice here (check your brake fluid.....lol), or just call me, Its what i do for a living bro. You still have my number? I'm on hol's at the moment, but feel free to call me and i can make arrangements with the boys to sort it out for ya..

Cheers

Dan

sell the patrol and buy a cruiser.....ha ha

did ya get it sorted Mako?

finally got it sorted, got off my butt and went to an auto store and got a can of CRC De-squeak, just pointed it though the slots in the mags and coated the disk and wamma, no squeaks

I will have to get me a can of that stuff.  My drivers side brake pad is shitting me BIG time!

yeah im glad i finally sorted it, used to hate the squeaks, spewing i never sorted it earlier now

Always machine the rotors and use bendix brake pads and you should be good. I would be very reluctant to put any chemicals or groove the pads as this will cause problems and you wont get the the best braking possible out of the patrol.  No short cuts with brakes!

Getting all my brakes done soon when I get new tyres all the way round on my Outback. Probably get my mobile mechanic to do it as he's the best Suburu mechanic around, used to be a mechanic for the Subaru World Rally Team so he has a fair idea what's going on with them.

Cheers
