My front disc brake was squeeky so I put a drop of oil between the disc brake pads... Now the brake has lost all it's stopping power, even after I have wiped the pads down. I read on another forum that the oil will soak into the pads and they will have to be replaced. Before I go jetting off...
I just bought a new Mongoose Tyax with Q3 hydraulic disc brakes.
They were feeling fine yesterday morning and then last night the brakes were really spongy.
Is this a sign of air in the line or what are some other things that could be at fault?
