Hi,

 

I just wanted to ask it's common for mk3 Octavia's to suffer with brake sqealing if it's not to do with the pads getting low?

 

Then also what is the best lubricants to use and where to prevent brake noise? I only ask because everyone seems to have different opinions so I thought I would ask here. 

 

Lastly if the pads are not low then can I take them out and lubricate them and refit?

 

Thanks in advance.

Hello, welcome to the forum.

 

1 - I've never had an issue with pads squealing. Are you sure your pads are ok? 

2 - I suggest copper ease grease (or similar) applied sparingly to the metal backplate of the pad.

3 - Yes, not an issue to remove then replace pads, make sure to refit everything correctly (retaining pins, shims etc.)

I haven't had this car long but when I checked the pads today there was a lot left on them. Definitely not a wear issue. As for quality I forgot to check what brand they were. I will check again tomorrow.

 

I noticed the brake disc has quite a lip on it also. 

 

How about for the slider pins. Is moly ok?

Terrible suggestion…. Copper grease is an old school thing used when there was steel on steel contact.

nowadays with alloys and such it causes galvanic corrosion and makes issues worse, not only that, dirt sticks to it and it slowly becomes a rubbing compound.

 

Not a single manufacturer or brake pad supplier or maker recommends the stuff and it serves no purpose on brakes. 
 

If you wanted to use anything, an extremely light coat of ceramic grease on the pad tracks, not on the backing plate which is a pointless location. Ceramic grease insulates.

 

But the main cause of squeaky brakes is either loose fitment in the carrier or build up on the disc/pad material that needs cleaning off

Yeah I don't use anything on the back of the pads either. I am going to take the wheels off tomorrow and clean the brakes with brake cleaner or try to work out if there is anything obvious.

Moly is not ok for sliding pins. Best from aftermarket is TRW PFG 110 or Febi 31942

Or nothing, if you have ATE brake system with rubber inserts.

Even with rubber inserts I’d be using red rubber grease on the slider inserts  

 

Any other grease can cause the rubber to swell and bind, causing brake sticking

To point 1: ATE and experienced users of this forum are in different opinion.
But with TRW system you should grease them always; but correct grease should be used.

Plenty of forums in Russian about this- guys are fighting with sensitive nonstop sticking brakes of various Korean, French and Japanese cars- and looks like TRW PFG 110 is best grease for pins.
