Brembo Brake Squeal

[Erni902]

Yeah I do hope so too dave. I found myself not using the brakes that much and just letting off the accelerator until suitable revs then changing down through the gears to help me slow without the squeal lol then when at a junction id put her in first to slow me right down then knock her into neutral and when at a near stop id use the handbrake to bring to a complete halt. The rears squeal a little when I apply the handbrake at around 3-4mph but nowhere near as bad as the fronts did.

I fear that if this doesnt fix it and changing pads doesnt fix I may revert to standard as Im just not using the brakes to their full potential anyway so its a waste lol. Really hope this is not the case but we shall see. Cheers for your help and advice Dave its much appreciated.

10 miles of quiet blissful driving later and the squeal returns!!! pads it is then!

Ive just fit CRN 40 groove on friday. Before i did that i was getting some squeal. After fitting CRN im still getting some squeal so i don't know if thats something to do with discs and bedding them, but i didn.t follow any procedure.

Well Ive been looking around the internet on all manner of forums and the general consensus seems to be that the Mintex pads are the cause of the squeal. All different variations of discs and calipers have been used by people out there and many are having the exact same pitch squeal, with the common denominator being the Mintex pads.

Ive had CRN discs before on the vr-4 with stock calipers and red stuffs and never had a drama at all. Next step is to swap for red stuffs and see what happens.

Hmm very interesting, i would blame CRN 40 groove which came as Pagid discs.
The squeal im getting is very high pitch and only when applying a little preasure under low speed.
I have EBC green pads and previously had some sort of discs (don't know make as i got them with calipers) and there was no squeal at all.
The squeal is very annoying and is not funy any more

Hard pads are always a significant factor in brake squeal. Discs can make a difference too. Brembos suffer squeal more readily than many other types of caliper too.

My understanding is that the pads need to release from the disc properly to help the squeal issue. EBC use a stickyish rubberyish backing pad that adheres the pad to the piston which I am pretty sure is designed for that purpose. I have often wondered if getting hold of some of that material and applying it to the backing of any pad will help reduce the squeal.

Maybe it is a combination of CRN 40 groove (Pagid) discs and EBC green pads which is likely to cause sgueal?
Interesting what pads do other members run with CRN discs, maybe worth to try different pads? Maybe just try standard Pagid pads as CRN come as Pagid?

[horndog]

I use CRN with Mintex 1155
I get occasional squeal, at low speeds if I have had them hot

Thats exactly what get, are ur discs Pagid?

No CRN Groved discs

[fassi1]

Thats what i bought too directly from CRN but discs had written on the outer edge Pagid, thats another think which i dont get, does CRN actualy manufacture discs themselves?

[horndog]

Mine were supplied and fitted by CRN, so I didnt have that good a look at the discs themselves

the only combo i know of that will not squeal is OEM brembo pads and Rotors (for anyone), but they cost any arm and a leg,

that said i have NEVER had the brembo squeal people complain about,

ive only ever used Bembo rotors, and what ever pads i could afford at the time,

anti squeal spray or gel, (not copper grease) between the pad and shim and between the shim and the pistons.
a very light coat of lithium grease on the guide pins.

i've had oem brembo pads, EBC Red, stoptech, endless, and some other cheap pads i cant remember there name.

I've no idea if Pagid discs cause an issue or not. EBC Green are not that hard in the brake pad compound scheme of things, so that shouldn't be the major issue.

Brembos are well known for squeal, apparently some Aston Martins have Brembos fitted and owners have demanded refunds on the whole car due to brake squeal?!

Have a look on the MLR to check out assorted fixes for brembo squeal, there are many things that people have said works but almost nothing that works in every case.

Sounds like solution to the problem
I think silicon greas should do the job as anti squeal. By lithium greas do u mean white lithium greas like this

or lithium bearings grease

ive only used specific anti squeal stuff as its sticky, not slippery like grease

and the second. need some high temp stuff as you dont want it coming off under heat,

i don't suppose you have the manufactures name of the ani squeal spray/gey?

[Gly]

the spray was a CRC product? and the paste i cant remember, it was sent to me a by a member on here years ago and i just ran out,
and cant find it again!

[Davezj]

I was wondering if there was a product that looked like the stuff that come fitted to some brake pads I have used in the past which was like a sheet of bitumen, thickish material that never seems to dry and remains slightly tacky. I think they were Frodo pads. It was a bit like the sound deadening sheets you can buy. It obviously was not the same stuff as it would need to be very high temp stuff.

[fassi1]

Ill give this go
http://www.ebay.co.uk/itm/Mintex-Cer...29829991133322
and i have high quality lithium grease used on car bearings so shoul be able to take high temps.
