Squeal While Bedding-in Ebc's

Hi,

Just put EBC Greenstuffs and some new rotors and I am getting a massive squeal(loudest I've heard brakes squeal on a car) if I brake below about 15 km/h. This doesn't happen for a bit after braking from speed, or the first stop or two. It also didn't start happening till about 80km after I put the brakes in.

Should this be happening while the brakes bed in? In the instructions for the pads it indicates there may be a bit of noise for the first 500km but it should die down over this time. It has been doing this for 300km now and if anything today it was worse.

I have taken the car out and done the few stops that I usually do to bed in.

I know the steps to take to get rid of the squeal but I'm just wondering if there is any point until I'm past the 500km mark.

Did you machine your discs before putting the pads in or at least rough them surface up with some course 50 or 90 sandpaper ?

I put EBC greens in my car recently without doing anything to my discs because they are in great condition. Now, my breaks squeal a bit under light breaking until I get some heat into the discs, then it's all quiet. If they do start to squeal, I'll machine the discs.

In my 32, I used to get brake squeal everywhere except the track with Winmax, NISMO, Ultimates and Endless SSS pads ( had machined discs or new discs each time also ) so.........

I cleaned "everything" I could but still...........

I didn't install them because I didn't have time but I think that was the problem. After playing with the pads to try and stop them squealing with no avail I bought some stuff from CRC that you spray on the discs themselves to actually stop squeal. That worked so I guess the shop didn't machine them, next time I'm just gonna wait till I have time and do it myself.

Stuff you spray on the disc itself ? :P Thats a new one to me. Will be interested to see if the results last.

I tried the stop-squeal that you spray on the discs but it doesn't seem to have helped. Couldn't get to the inboard side of the rear discs because the heatshield goes all the way around, but I did the fronts both sides.

Yeh I'm pretty sceptical about it but the 'spray' wore off the rotors very quickly and just left a few lines where I guess there were imperfections. If these wear at the same rate as the rotor I can't see it being too bad.

I had the same squeel as well after fitting EBC greens and machined discs...its gone now...only happens occasionally when I reverse the car out of the garage early in the morning while its cold.

Hope you enjoy the brake dust that comes with it :D

      @joshuaho96 Hmm considering the drama you've seen/experienced, have you looked into getting a built complete long motor shipped from Australia?  Considering the AUD is basically monopoly money when compared to the USD, at a glance this seems like a good option?

      Bloody Skylines, they put you through the bloody wringer! Stick at it! Stunning drag strip BTW! Where is it? Can see part of the name on the slip and probably should just Google it!

      I mean the other day I had to walk someone through diagnosing why their timing belt was walking off the cam gears. At least one of the issues was a bent tensioner stud. Local mechanics have found runout on the CAS mechanism causing weird failures. I'm also no saint here I've documented some of the things I've had to learn the hard way. Something I discovered recently is that my CA emissions catalytic converters weren't even welded correctly to align the downpipe to the main cat and they tossed the support bracket that goes from the transfer case to the downpipe to support everything there. I spend a lot of time chasing down these decidedly unsexy problems and the net effect is it feels like I never actually get to the original objective (flex fuel, VCAM, oil control, cooling, etc).

      At times with how you make everything sound, all I imagine Americans doing when they see a gtr is standing there looking at it and bashing it with a gun like how a caveman would with a club and hoping it fixes itself

      I think this is just a product of how the US market works for this stuff. Shops are expensive and there's no real way of knowing what kind of results you're going to get, people don't really have the institutional knowledge. I have heard too much at this point to really put faith in anybody "full service" except maybe DSport and they aren't really a full service kind of shop. If you go to the right place I have no doubt they'll get it right for you. Some locals have set it up right but the cost really is nuts and even now they're still fighting issues. And you know I'm a crazy person who thinks things like twin scroll, relatively short low-mount cast headers, PCV recirc to intake, recirculating BOV, right-sized for ~400 whp, MAF load, validating all of that to a standard comparable to OEM test programs, etc are relevant. For what it's worth, multiple local owners at this point have been stuck in a perpetual cycle of blowing a motor -> getting someone to rebuild it -> some missed detail causes the bearings to wipe and spin just outside of break-in mileage or drop valves or some other catastrophe -> cycle repeats. I usually only find out about this because I'm perpetually helping random friends with diagnosing car troubles, Skyline or otherwise. The single turbo stuff if I'm honest is mostly secondary, it just doesn't seem to achieve the numbers in the ~2000-3000 rpm region that I would expect given the results I've seen here or in Motive's videos. I don't really know what we're missing here in the US to be causing this. Lots of people like to emphasize the necessity of finishing the project first and foremost, but I'm not made of money and I can't afford to be trashing a 15k+ USD engine build with any regularity. Or spending my relatively limited garage time these days unable to triangulate problems because too much was changed all at once. Also, even if it isn't a catastrophic failure I would consider spending the cost of single turbo conversion with nothing to show for it to be pretty bad.
