Screeching Front Brakes

Mine does this a bit. Think it’s getting better. I was under the impression new bikes don’t have a dab of copper slip on the back of the pads which would probably clear up the issue.

 

I’ve previously dabbed coppaslip on pad rears but no longer,seen an ebc video about pad manufacture very interesting,expressly advise not to put anything on back of brake pads and advise absolutely no claims of any warranty whatsoever if anything is applied.

 

Any particular reason?

 

It’s debatable I found the video in a link from a guys channel (the workshop) on you tube,it started off as a dig at delboys garage where he advised putting coppaslip grease on pad rears (as recommended by ebc he stated),this is where it got heated guy saying delboy was straight up lying about the ebc advice,the ebc video he showed was against putting anything on pad rears ended up a bit of a rant (not from ebc but workshop channel guy) about how the backing plate is porous etc,etc,phew I hope that explains a bit,btw I’ve used copper grease myself for years so that surprised me,not opening a can of worms as I’m not an expert but ebc do make the pads there was also some comments on heat transfer in the rant.

 

I have used copperslip on the rear of pads for years. As well as being effective in stopping pad squeal, if you use a very sparing amount, I cannot see how it could cause a problem. Give it a try....if it doesn't stop the squeal, you can clean it off with brake cleaner and noone will be the wiser.

 

Ah nice one thanks for taking the time to type all that!

I will see how it goes but if mine stays the same at some point I’ll pop a little smear on the backs.

 

I had the exact same problem with mine...... warranty claimed for a change of pads then discs now its ok..... I took the pads out yesterday and copper slipped them, cos I'm old school.

 

Yeah i looked at that a few days ago, it does make sense..... but my bikes never see rain or salt so all's good, I'll stay old school hahaha
Must of been a bad batch of pads or discs that's affected out bikes mate, as long as it gets sorted I'm easy.

 

Picked my new (Ex Demo) RS up Tuesday, I noticed a squeak from the brakes when I test rode it and mentioned it, the dealer promptly ignored me and it was still squeaking when I picked it up. I took it back to them Friday and they took a look but simply said the screeching is normal and told me not to try anything on the back of the pads.

Not really sure where to go with this, even my mate could hear it when riding with me through town.

 

It's not normal, far from it.... just had mine changed for the exact same reason..... rattling, sqeeking, grinding horrid feel.

Take no shit mate, it's your hard earned money....they provide a service, not a service to take your money and run.

 

That's exactly what mine does its so irritating the noise when pulling up

 

I would say it makes SUPERFICIAL sense. The thing is, brake pads are backed with steel and the calliper piston is generally steel riding on a synthetic rubber seal even if the calliper is alloy. The need for galvanic protection first needs to be established. Most of the specialist brake greases are now copper free to be safe.......
So the issue now is not, as Shakespeare would say “to grease or not to grease” but which grease? Grease damps out the vibrations that cause the noise. £5.19 a 75ml tube at Eurocarparts.

 

Update on brakes..... the copper slip worked great, no sqeeking, chattering or clunking even when manoeuvring around the garage.
Copper slip may not be the best by today's advances..... but for me the bike never sees rain or bad whether so what's the harm

 

Fairy nuff but in slow time clean up and replace with

Those fine copper particles may just cause galvanic corrosion because of pesky electron movement. You can afford £5.20?

 

Them little corrosion bast@&d's won't get a chance to do that matey ..... I'm an absolute nut job for servicing, cleaning, maintenance and thanks for the heads up on that product I will give it a try.

 

I always use ceratec on my car much better than the old slip...

Guess I should ignore the dealers advice and use some on the back of the pads?
