My bus is still of the road awaiting engine but seem to remember that it had horendous squeaky front brakes on braking that I could not cure.
It has standard brakes all round.
I tried new pads.
I fitted shims behind the pads.
and I copper greased everthing
And they still squeaked.
78 bay my disc are 1yr. old with pads but when driven for a while they squeak when you apply gently,does copper grease dry out after a while as this is what was on backs of them.
or should i just replace pads and if so what make are best ,cheers
