instead of just turning my rotors I'm going to throw on some new ones - so I'm thinking I should do the pads as well - will I have to bleed the brakes to get the new pads to go around the new rotors? Advice please
Definately get new pads to go with the new rotors. You will need to compress the pistons in the calipers to get the new pads on. The best way to do this (but not the only way) is to loosen the bleeder screw and compress the pistons forcing fluid out the bleeder valve. This method prevents shooting old, possibly contaminated, brake fluid back through the system. You can also compress the piston on the caliper without opening the bleeder valve but this could cause troubles by causing the master cylinder to overflow and could potentially damage expensive ABS components. If you use the first method you will need to bleed the brakes but not very much if you are careful to close the bleeder screw as soon as you compress the piston. Thats what i would do if i were you
ok thanks very much. I'll use the first method. Now I've done this on my older vehicles and I have always clsoed the bleeder as soon as I compress the piston - so I shouldn't have to pull the back wheels and bleed them also right?
I might suggest leaving your brake system closed. Utilize a C-clamp to compress the piston with the aid of an old pad. Don't get horsy with it, just compress it slowly. Opening you brake system requires bleeding, if you have not added fluid due to loss, you will not overflow your resevior(sp), or damage ABS. Many brake pad/rotor replacements done this way on 2001 and 1999 ford's no problems at all.........................my thoughts and experience.
