What size is the bolt to the brake caliper for 1994 Cadillac sedan deville?

Answer 1

The Rear Caliper Bottom Bolt head size is 12 mm. The Top bolt is enclosed only making it a slide bolt therefore you cant and really have no need to remove it. So the only bolt you should remove is the bottom 12mm head bolt. Then there will be a 14mm bolt that will hold the Emergency Brake Cable Bracket to the Caliper. Loosen this bolt and remove the Emergency Brake Cable Bracket from the Caliper. Then pry the bottom of the caliper up off the disc. This will allow you to swing the caliper up then push the caliper back to slide the caliper off the enclosed bolt slide at the top of the caliper. This will allow access to the inside and outside pads to remove them and allow you to press and rotate the Piston (Push and Twist-in Pistons) back into the Caliper with the right Brake Caliper Compression tool. The rear two Caliper Bracket bolt head sizes are 18mm. You must remove the Caliper bracket in order to remove the rear brake disc. The Front Brake Caliper Bolt is a 3/8" Allen head bolt. There will be two bolts holding the front calipers to the Spindle. The Front calipers are standard push-in Pistons.
