Buick Riviera Caliper Replace/Remove

How Do I Get The Top Caliper Pin Loose From The Rear Brake Caliper? The Bottom Bolt Was No Problem,what About The Top One?

What Size Is The Factory Torx Head On The Top Of The Rear Caliper For Removal?

Does The Top Where The Cap Is On The Caliper Have A Bolt Under It.instead Of A Bolt It Has A Cap With A Little Rubber Nipple Sticking...

I Replaced A Caliper For My Riveria On Right Rear Side Replenished The Brake Fluid And Now No Pressure From The Brakes What Do I Do

Other Than A Bad Caliper,what Could Make Your Caliper Stick. I Had Sticking Caliper,replaced It,the Rotors And Pads,bled System And It...
