just changed my rotor and pads, however I did not use degreaser to clean the new rotor and left the factory coating on. now when im driving the rotor smell very strong and a little smoke. I also did not bleed the system(don‘t have 2nd person to help me). however the brake calipers seems working fine when I push It in with G-clamp. I‘ve only driven it for less than 2km. do I need to bleed the system if I did not dismantle the oil line?
The coating on those new rotors should have been cleaned off before installation because that coating has now been picked up by the pads and is acting like a lubricant. The last thing you need is a lubricant between the rotors and pads. Removing it now will take care of the rotors but It may be too late to save the pads but you could try taking them off then cleaning them with brake cleaner. Might work depending on the type of pad material but if not, best bet is to get new pads. Bleeding is normally not necessary if no hydraulic connections have been opened and there were no leaks of fluid.
The most common reason for smoking brakes is a stuck caliper. If your car's brake system uses floating calipers, they are designed to slide around to function properly. Calipers sometimes become stuck, locking the brake into place. This creates enormous friction as you drive, creating smoke and a foul odor. Stuck calipers are usually caused by dirt or corrosion that hinder the caliper's movement. You have to take it to a certified mechanic to fix a stuck wheel cylinder or caliper.
