How to stop your brakes squealing 101

When I got my RB74 pads, they were rather quiet. After several months though, the right front brakes started to get a little noisy. When it got to the stage where it would squeal on every slowdown, I decided to see if I could fix it (well, I put it off for a few weeks because I'm a lazy bastard). Here's the brief rundown on how I did it.

1. Buy some red gooey anti-squeal stuff from my local spares shop.

2. Buy 1-2 sheets of 80 grit emery paper from the same shop (around $1.25 a sheet)

3. Jack car up, remove offending wheel.

4. Remove clips and springs from pads.

5. Remove pads from caliper.

6. Sand back the pads on the emery paper until the glazed surface is roughened up. There may be some scoring marks left on the pads, it's not essential to get rid of every little groove.

6a. If your discs are badly scored, get them machined. Maybe you should figure out whether or not they need machining before you sand the pads back.

7. If the discs are fine and you can be bothered, give the discs a quick once-over with the emery cloth. It's pretty difficult to make even a light indent in the discs though, so don't worry too much.

8. Put red gooey stuff all between each layer of pad and backing plate, as well as on the back of the plate that sits on the caliper piston.

9. Put pads back into the caliper after the red gooey stuff goes tacky.

10. Bend the anti-squeal spring in the opposite direction a bit, to give it more tension for when it's in place.

11. Put spring and clips back in, put wheel back on, etc etc.

12. Test everything.

13. If you crash your car for any reason, don't blame me (disclaimer).

It's weird how only my right front brake started squealing. The left front one has remained quiet all this time so I didn't bother doing that side. I only fix what's broken :)

I had bendix ultimates and they squeeled like a beatch and drove me nuts. I went and bought some of that anti squeel spray but it didn't help me at all ( i still had anti squeel shimmy things in there though). When I changed brake pads I got LUCAS ones put in, and they have not made a single noise ever!

I'm so impressed with these pads, they stop beautifully, don't leave my rims as filthy as the bendix ones, and they don't squeek!

So there's my advice, use the Lucas pads! (I've heard the RB ones are a bit squeeky too!)

its mainly just the dust that makes the pads squeal after awhile. i have ferrodos that are hell dusty. i just got some anti-squeal from my work, cleaned up the discs and pads, put it on the back of the pad, includin the spring and it has never sqeualed again.

I've had Ultimates, from readings I was expecting them to squeel so I bought my self a tube of PBR anti-squeal adhesive, slapped it every where over the back of the disk and antisqueel shims.

They never squeeled so it worked. :huh:

The car was only driven on the street and never saw anyhard braking.

Just cross hatch the rotor with emery paper, around 80 grit as mentioned. The sqealing is caused by dust build-up in the grooves of the rotor. Don't be scared of giving them a good rub too.

My vote, the 'red gooey stuff' is not required.

      GOT SUM's RB34

      By klutched · Posted

      This morning I carefully reinstalled the manifold and started looking at a couple of things I need to do.  Heat wrap arrived sometime today so I popped into the shed with the missus dishwashing gloves and started wrapping the first half of the dump and the screamer/plumb back.  Once I do the second half I'll be able to final fit the turbo and exhaust up.  Also pulled the harness out today and started terminating it at the ECU end. A connector is done, just need to run the remaining wires that arent in the harness - 12v, gnd and couple I/O

      Thanks for all the replies! I also wanted to ask if wheels that were fitted on Ford Falcons would fit the 350GTs as well? In the area I'm at there aren't that many options for secondhand wheels and new ones here are way out of my budget. From what I've seen, most of the wheels that are available that were fitted on Ford Falcons have an offset of +33 to +36, with a centre bore of 70.5mm whereas the stock 350GT's ones are 66mm, can't seem to find any hubcentric rings that fit that difference though.

      215/45/18 tyres are probably a little on the low side compared to the factory tyre, it should be closer to a 245/45/19, which will get you about an extra 11mm of height, and should make you speedo read a bit closer to reality. 245/45/19s will be a bit too far the other way and you risk a speeding ticket as your speedo might read slower than your actual speed.  245/40/19s would be correct if you are going to 19in rims, they will give you a similar total diameter to the 245/45/18 tyres.

      That's something I forgot to put in my list. The aggressive anti-squat in R32 is a f**king menace. I still need to decide if I'm going to drag the subframe out of my car and weld in the GKTech corrector kit. The main reason to dither is the need to switch to spherical joints in the lower arm to account for the twist induced in the rear pivot caused by lowering the front pivot. And yes...we do put better subframes in R32s, and I wish I'd gotten an S14 one instead of an A31 when I did the "take off and nuke it from orbit" HICAS delete all those years ago.
