My Swift is having a problem with left side brakes, the brake pads are newly installed and of a good brand. When I press the brake a wired sound like "squeezing" or a rusted spring appears from the left side. I have got it checked 2-3 times to different mechanics but when they apply oil inside the piston and grease on the sides of the brake pad it gets aways but after running for 4-5 days it appears again.
It is the solution to it?
