Replaced the rear brake pads on my brothers 03 Sharan about 3 months ago the discs looked OK only a small lip on the disc edge with Bosch pads after 2 weeks you could see the pads only made contact with about 2 cm of the disc so thinking the discs maybe worn I replaced them both and the brake pads again but only 2 cm was being contacted on the discs again.
After 2 months the pads had full contact to the full disc but now the first 2 cm of the discs are starting to go blue as if the pads are contacting there all the time.
Both sides are doing the above.
With the handbrake off the wheels spin freely and when I replaced the pads/ discs I wire brushed and copper greased the pad carrier where the pads contact, checked that pads moved freely in carrier, checked the sliders moved freely, wire brushed and removed the rust from the hubs before fitting the new discs.
The front brake pads have now been replaced with Bosch pads and are starting to only contact with 2 cm of the disc?
I have not replaced the discs but have before fitting the front pads have done the same as above wire brushed and copper greased Etc.
Anyone else had this problem or am I going crazy?
Thanks in advance for any advice.
