Brake Pad Fail!

[andyglym]

OK folks, over the last few years I've had the brake pads detach from the backing plate 3 times! 2 x rear left and 1 x front right. Any ideas Pagid pads have been used throughout.

Pad separation usually caused by excess heat you'll maybe need to be fitting some better quality pads like EBC or the likes.

Excessive cleaning could be a factor

Magma overdose.
no. I am not kidding.

Interesting, what makes you think this?

Sodium mercaptoacetate is organic, reacts with iron oxide i can not post the molecular type here but it looks like it it literally eats away iron. If your pads are organic and are a sintered type, large quatities of magma really dissolve them.
As for the other ingredient, ethanol, we all know it is a solvent.
the general idea is that sodium and ethanol if not rinsed properly, or in large quantities, can alter the structure of the pads and loosen the materials structure.
a friend of mine who is a chemist warned me about wheel cleaners and said that the proper cleaning way is to remove them from the car when using the chemicals frequently.
he knows his stuff, he works in the oil industry, head of a department at a refinery.

Having chased followed you for a fair few miles Andy I can confirm you are no rolling roadblock

Seriously though what Stephen said, EBC redstuff pads

Solid info that

Oh no Andy they'll have to change your nickname at Halfords
They won't be able to call you ' Volcano ' any more due to the amount of Magma you use .

All Greek to me, but like I said, excessive cleaning

 

[ExMX5owner]

I assume the rotors are good.

Sillier things have clearly happened... Sorry, I couldn't resist it either... .

 

[Althulas]

None of your calipers sticking either to cause the excessive heat?

drastic differences in inside/outside pad wear.

 

[t-tony]

Common reason for friction material coming of the metal backing is the pads seized in the carrier. This makes the backing bend because it can't slide freely and this flexing brakes the bonding.
