Changed front brake pads, because that is where the noise is coming from. its the right hand front wheel. i look at the pads and they still have a lot of meat on them, but changed them anyway with some fero's or whatever they are, but still no luck, was ok for like 2 days, but now squiling like crazy again. went to supercheap picked up some spray to clean and take away noises brakes, still no luck.

what do i do now? i pull up at the lights and once im almost stopped ( 10k's a hour ) this horrible squiling starts until i slam the brakes hard!

any idea's?

thanks

Itll be the discs, feel up and down them for uneven-ness and cracks. new pads will last for a bit until the cracks in the rotors cut into them and you get un-even disc/pad contact again.

You need to take the pads and the discs off and take them to a break specalist and have them machine the rotors and chamfer the pads. If the rotors are gone beyond the machining point then you will need new discs, I recomended DBA Slotted, or if you want to spend more money, DBA Slotted + Dimpeled, which are also gold passivated and zinc treated.

My front brakes were fine but would squeel like a pig just as the car was coming to a stop. My front rotors were glazed due to overheating and needed to be replaced (too thin to machine).

I had the same problem, i got my rotors machined as i had plenty of meat left on em... solved my problem too

I have this problem, I had my discs machined and pads replaced and they were noisy as hell, I took the car back and they looked at it and when I got it back they were better but still noisy..

stock rotors and Lucas pads, I havnt been back since because I have a problem with assholes pretending they know my car.

I'll be trying the spray then if that doesnt work I'll pull them down myself and do them myself..

they were bled , and are standard brakes. ive tried anti squil spray but no good. might go for slotted discs i think, thanks for the replies

I've got project mu slotted rotors and endless pads and they squeal. Having slots doesn't stop it squealling.

Many pads these days squeal especially performance pads under light braking.Generally if the rotors are machined and the pads bedded in properly it will lower the chances of squealing.If you have the metal shims still on the pads take them off and try the stick on anti-squeal which goes on the back of the pad.These are available from Race Brakes Sydney for about $10.

If you have performance pads or the brakes were not bedded in properly it may be to late though.

I'm actually not sure what my pads are (haven't had to change them yet) but I've personally found that my biggest problem is when my stock rotors get wet. They get a layer of surface rust almost instantly!

First few stops they squeil at low speed, but after that they're ok again.

      Cas issue

      By GTSBoy · Posted

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.

      RB26DETT Sketchy boost mod?

      By Duncan · Posted

      Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.

      Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.

      Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
