Brake Pull

[iah1980]

Hi, recently experienced the car under braking pulling to the left. I finally managed to have a look at the slide pins and they were fairly stiff n/s and lubed up nice with some lithium grease. However, on the o/s the lower slide pin was stuck fast, after letting it sit for while in lithium liquid I managed to free it, cleaned it up thoroughly and placed back and it was sliding very freely. The outside brake pad on the o/s side was tapered quite considerably but I had to put it back in until my new pads arrive. The problem is still there so the question is will the tapered pad still give the brake pull (silly question maybe) and replacing should solve the issue or do I need to investigate the issue further? If you could offer some information on this it would be appreciated.
