Lound Squeaky Brakes.

[dclarke]

Hi

I know in the scheme of things this is a relatively small issue but its driving me and my wife crazy.

My 3 week old 3R (No track days yet) has developed very loud squeaky brakes which make me sound like a HGV or London bus everytime I pull up.

I mentioned this at my 1000 mile service at Mole Valley, but Paul said "the type of brakes that Nobles are fitted with are prone to brake dust squeaking and I will have to live with it."

But it's just so loud and that's with the extra sounproofing!!!

They have been cleaned by MV and I have applied Break dust cleaner but still no joy.

Does anyone else have this problem?

Is there really nothing I can do about this issue?

Surely all Nobles can't all sound this bad when coming to a halt?

My Tuscan never Squeaked and I sure the pads must be of a similar standard.

This is really spoiling my driving pleasure. Any advice/help much appreciated ?

Den,

At the last track day Lee said that some brake's squeal more than others. I have no idea if the R has different brakes, but given the GTO's don't sqeal it seems a little silly that a "refined" version makes the noise!

I'd give the factory a ring on Tuesday and speak to the service bods at the workshop and I'm sure they will be able to advise on what to do.

In previous times I've applied "copper ease" to the rear of the pads (making dam sure I didn't get any near the front of them) to stop squeal and it's worked a treat.

There also seem to be some other solutions out there

You can google more by putting "stopping brake squeal" into google.

If they are brand new, you need to bed them in properly. Read the prevention section of the following :

They should squeel less once properly bedded in, although jousts suggestion works well on the Elise for high performance pads (well pagids anyway). Not sure if its a universal solution though, or to do with the way pagid pads are a little small for the calliper on the Elise.

Sounds like a track day needed!

Dennis, why should you get into DIY on your brakes - you just paid 50-odd grand for a toy - if this persists then IMHO it is Noble's responsibility to correct the condition! This makes me wonder how (or even if!) both the factory and the dealer tests their cars before customer collection - I'd have thought it would be evident in testing - or do they wear ear-plugs?!

[dclarke]

Thanks for all your suggestions.

I'll give the factory a call and see what they suggest.

To be fair to the guys at the factory & MV the brakes did not squeak when the car was delivered.

mines done 3500 miles in me 3R now and still squeals dispite H R Owen taking them out and chamfering the edges and copper grease, but the factory did say last thursday that the pad manufactures are looking into it. Does not do it on heavy braking only just as you back off the pedal as you stop. They will get it sorted.

There will always be a difference between a racing / track pad compound and a normal / high performance pad compound.

From my experience (of racing saloon cars and) of using racing pads fitted to my ('92) 9IIRS, they always squeaked on normal road use with light application. This is due to the pad vibrating against the disc and in the calliper. De dusting, copper grease and de glazing the disc and pad will give a temporary fix. Road cars with normal disc pads sometimes have anti squeal shims between the calliper pistons and the pad backing plate. This tilts the pad slightly (couple of thou) to provide a leading edge for the pad to meet the disc rotor.

My ex missus used to nuts when we were in the car, (In a strong Geordie accent) "You pey all that monee for this corr and it meeerks that rakkit". Never did take her on a track day.

The only solution I can see (subject to Lee's comments) is to get different pads (compound) fitted which will cure the problem for road use, then see how you get on with them if you are doing track days.

Hope you enjoy your 3R experience. Mine (R35) is due in 3 weeks or so.

As above, high performance pads squeak if you use them gently. Especially if you don't bed them in. Given that you've just bought a high performance car, I'm surprised your first inclination is to talk to the dealer and not just bed them in first? You have new discs and pads so it needs doing.

If you don't bed them in, they'll just get nicely glazed and squeak more.

Sorry for intruding chaps but I've got some Martian grade abduction special pads on my beetle and they squeal like a hog that's just realised it's wandered into a BBQ spit twirling competition.

Any modest application is almost embarassing but as 3rrt and DanH have suggested, this isn't untypical with some extreme pad compositions: come to think of it, my old Cerby's AP pads were appalling too but then, from what I recall of a Clarkson video in which a Speed 12 heaved to a standstill in front of him once, it too screeched like a grating banshee.

Fecking annoying, nevertheless. Still, the solution does seems to lie in the application of severe pressure to pedals 3 and 2...
