Brake pads

[stranger12]

Hi guys

When you hear a robbing sound of metal on metal on ur disc, it is a sign of low brake pad , right?

I remember reading somewhere saying when pads get low they have this built in feature to make that noise and make you aware of the need to change

The pad seems to have some meatbon it still

How is that sound produced, do pads have a metal that scratches against the disc?

No its badly maintained brakes.

[stranger12]

well I changed the pads 2k ago to sintered ebc

and rebuild the caliper 3k ago( last year).

I haven't since then opened the caliper to clean it etc

but I know most pads have the saftey feature of making the metal to metal contact sound when they wear down to limit but don't know how it works.

my assumption is if there is any contact to the disc ( metal to metal) then that is pad so why manufactures implement this ?

Could be either.....

Only takes a few minutes to whip the pads out and have a look.

Why not take the pads out, if they still have more than a few mm of pad material on them, clean 'em up with.a bit of coarse emery cloth and refit using some copper/graphite grease on the backplate and abutments at the end of each pad.

If worn low.....replace pads and check caliper pistons and slider pins move freely before reassembly.

yep what I do over the weekend .

I wanted to get some opinion and maybe get the pads and change any way

after I realised they are £40 a pair hence £80 I am thinking of first taking the pads off and checking
unless someone here has £80 to donate

Shop around - £40 sounds like too much!

Change the pads when there is 3mm or less of the friction material remaining, or you run the risk of trashing the discs themselves.

You can usually see how badly the pads have worn, just by looking at them - like you shound be doing once a week.

yes do that but there are so tiny anyway that you can't know .

they are about 10 mm brand new I think but I agree and do what you say

What I've found through experience is even though you can look at what's remaining on the pad like the picture above, it doesn't account for uneven wear.

I've had pads out where the pad still has a couple mm on one side, but metal on metal on the other end.

Usually down to a sticky piston or alignment out.

There are times when the pistons and seals can be nice and clean and still have a caliper that causes uneven pad wear.

I borrowed this pic but it shows a pin that is quite corroded and can cause all sorts of problems.Quite often if a caliper is allowed to get to this state then the other pin that the caliper sits on will be just as bad.

No excuse for bad maintenance
