Need to replace rear rotors. Took brake caliper and bracket off and discovered deep grooves in the rotor. tried to remove rotor but wont come off. Noticed two phillips head screws on rotors and wandering whether or not I have to remove these two screws in order to take the rotors off or is it the rotors are simply stuck and need to be pryed off.

Are there small retainer clips on the studs still? More than likely its just rust built up on the center hub. Take some sand paper to the center hub, as long as e-brake is released and caliper is off, it will come off. I'm not familar with the toyota sienna's but if they have internal drum e-brakes, I would back off the adjuster if they do.

Depends somewhat if it's a front rotor or a rear rotor. The most common problem will be "corrosion" that's binding the two metal parts together. If you are not trying to reuse the rotor after turning (many are throwaways now adays) take a large hammer and bang the outer edge of the rotor. The vibration should cause the corrosion to break apart, and the rotor should pull away. If your planning on re-using the rotor after turning use a large rubber mallet.
The front rotors have about a 3/4 inch common surface between the rotor and the wheel hub. You may need to bang on the backside of the rotor as you slowly turn the rotor in order to cause the two parts to slide apart. It can be a slow process, but you should see some movement (but it must be even movement around the entire rotor. The back rotors have far less common surface and a few good waps should break the parts free.

31 ft lbs for caliper to bracket, then caliper bracket to nuckle is.148 ft lbs for 6400 & 7200 lbs GVWR or
122 ft lbs for 9900 lbs GVWR or
221 ft lbs for 12300 lbs GVWR.
good luck hope this helps.
Testimonial: "thanks for the quick response!!"

Brake lines are not releasing fluid back to master cylinder. Open bleeder and see if wheel will turn. If it does replace brake line to caliper
An impact driver, No. 3 phillips screwdriver bit, and a hammer may be needed to remove the retaining screw. It is fairly easy to destroy the screw slots using an ordinary phillips screwdriver to remove the tightly driven screw (see photo).
