djrm Posted October 19, 2010 Share Posted October 19, 2010 Hi guys When stopping at low speed, my brakes seem to squeal quite a bit... they still work fine and make no noise at higher speeds, only at low.. Is this common? I know they are bigger brakes than most cars etc... I will be checking the pads later, could it be that? Thanks Ryan Quote Link to comment Share on other sites More sharing options...
UNABASHED Posted October 19, 2010 Share Posted October 19, 2010 might just need a bit of grease behind the pads Quote Link to comment Share on other sites More sharing options...

M13KYF Posted October 19, 2010 Share Posted October 19, 2010 copper grease or better still Aluminium lube Quote Link to comment Share on other sites More sharing options...
moonscale Posted November 24, 2010 Share Posted November 24, 2010 Try and stay away from any grease near pad materials if they contaminate the material this will cause more problems....something like a anti squeal kit should suffice click here http://www.ebcbrakes.com/brake_noise/no ... d_in.shtml New disc pads take some time to bed down, even if you are using new or turned rotors and during this time when the pad is bedding in to match exactly the geometry of the rotor the pads can make noise. The normal way to minimise this is to add noise reduction shims onto the reverse side of the pads which dampens the vibration caused by the pad which will "Chatter" slightly when not seated perfectly. This noise would go away after 300-500 miles but to avoid irritation noise shims are used to reduce this sound. There is no safety issue when a pad makes these noises during bed in, it is merely a cosmetic problem of the new brakes. You can obtain these from www.brakes4u.co.uk you would need part number ASK1 Hope this helps Quote Link to comment Share on other sites More sharing options...
Neilp Posted November 24, 2010 Share Posted November 24, 2010 cars with anti squeel shims still squeel if theres no copper grease on them. found out through experience Quote Link to comment Share on other sites More sharing options...
Vik54 Posted November 24, 2010 Share Posted November 24, 2010 Try and stay away from any grease near pad materials if they contaminate the material this will cause more problems. News to me ...surely correctly applied copper slip is a must when fitting new pads? Quote Link to comment Share on other sites More sharing options...

moonscale Posted November 24, 2010 Share Posted November 24, 2010 keep oils greases and lubes away from the brakes as the two don’t go together happily. Brake pads must be kept clean and grease free, even the grease from your fingers can sweat into the pad surface and reduce the brake pad effectiveness.

Neilp Posted November 24, 2010 Share Posted November 24, 2010 sorry but is it not standard practice to grease the rear of the pad? its pretty obvious not to get grease on the friction material Quote Link to comment Share on other sites More sharing options...
Chris`I Posted November 24, 2010 Share Posted November 24, 2010 sorry but is it not standard practice to grease the rear of the pad? its pretty obvious not to get grease on the friction material I think he means keep it away from the friction material, not the pad entirely. You are fine to grease the backing plate of the pad, just keep it away from braking surface Quote Link to comment Share on other sites More sharing options...
moonscale Posted November 25, 2010 Share Posted November 25, 2010 sorry not worded correctly here you go this might make sense lol “Molybdenum Sulphide greases are not recommended by EBC brakes on any part of a brake system because of their very abrasive particle content and their low thixotropism (means they are thin) . Also their low melting point means they can, in our experience migrate under vibration onto brake pads or the rotor hub and then “Spin out†up onto the pad surface. EBC has received numerous sets of returned brake pads and discs that showed streak lines where the grease had radiated out from the hub and pads that were black and polished on the surface and low in friction .After analysis the pads were found to have absorbed sulphides from such greases.†Quote Link to comment Share on other sites More sharing options...
Neilp Posted November 25, 2010 Share Posted November 25, 2010 So what would you suggest we use? As anti squeal shims only limit squealing when combined with a grease. My ebc pads had instructions with them saying where to copper grease I'm sure? Quote Link to comment Share on other sites More sharing options...
moonscale Posted November 25, 2010 Share Posted November 25, 2010 The only time i use grease is to lubricate the caliper sliders i have never smeared any onto the rear of the pad.in the bedding procedure you can sometimes get minor noises which occur in early pad life...bedding in procedure is normally 500 miles also you can get pad noise from some pads that do not have a chamfers these do help to reduce low speed brake noise.Also the bed in coating EBC apply to alot of there pads also helps to bed pads in quickly and again to reduce brake noise. But i suppose if grease works for you then dont change something that isnt broke Quote Link to comment Share on other sites More sharing options...
Neilp Posted November 25, 2010 Share Posted November 25, 2010 Sorry mate I'm not trying to be an arse but I'm just curious to what I should be using as copper grease has been a solution since my dads days in motoring lol. What should we be using? Quote Link to comment Share on other sites More sharing options...

What should we be using? Neil, stop getting your panties in a twist mate. Of course you have got to use copper slip - copper grease - squeal ease to help eliminate brake pad squeal caused by contact of the caliper piston and the rear of the brake pad. Most of this stuff is good to very high temperatures and providing you have not applied it with a ladle and you have not been to liberal with the application to the rear of the pad then all will be good and it will not disperse onto the friction material. If you are running big power and require something which will handle extreme temperatures then I would recommend PBC (Poly Butyl Cuprysil) which is good for up to 1200 degrees C This is what I use but any of the other stuff previously mentioned or similar will be fine for your track beasty Quote Link to comment Share on other sites More sharing options...
moonscale Posted November 25, 2010 Share Posted November 25, 2010 Im not saying you cant i dont personally use anything and have never had a problem. But i was just pointing out how careful you have to be mate you can contaminate the pad material without realising once this has happend then the trouble begins most people do still use it with a little finger nail splodge on caliper piston and the rear of the brake pad..... But have to say to elimanate this i dont use it and have never had a problem most of the pads that i have fitted(EBC as this it what i retail in)have the shim fitted....along time ago i had EBC greens and had squeal problems explained what i had done.....this is when EBC sent me another set and told me to fit them without which i did and guess what no squeal....so ever since i havent used it lol Quote Link to comment Share on other sites More sharing options...
Neilp Posted November 25, 2010 Share Posted November 25, 2010 What car do you run? I don't understand why it would cause it to squeal? Alex I know mate Quote Link to comment Share on other sites More sharing options...
spursmaddave Posted February 18, 2011 Share Posted February 18, 2011 Is applying a bit of grease an easy thing to do as my brakes are a bit noisy at low speeds too... gets embarrassing Is it a wheel off job and would I need to know much about what I'm doing , because I don't Quote Link to comment Share on other sites More sharing options...

It is a wheel off jobbie and the pads will have to removed one by one and a light smear of grease on the rear of the pad is all that is required. Alex.
