How do you compress the brake cylinder on the rear disc brakes of a 1988 Honda Prelude Si?

Answer 1

Takes a special tool. The caliber must be twisted as it is compressed. Honda DEALERSHIP TOLD ME I NEEDED A SPECIAL TOOL FOR THE CALIPERS BUT I USED A PAIR OF BIG WIRECUTTERS AND PUT THE POINTS OF THE WIRECUTTERS IN THE SLOTS AND TWISTED THEM WHILE I APPLIED PRESSURE. WORKED LIKE A CHARM!!!!! On my 89 Prelude Si, the slots in the rear piston were large enough that I was actually able to use the edge of my used brake pad. The brake pad slid PERFECTLY into the slot, and the size of the brake pad allowed me to grip it well with a good part of my thumb and a few fingers to be able to put some good torque into it. Also, using the brake pad meant that it used the entire slot on the piston, so that pressure is distributed more evenly; no slipping and scratching things up with a pair of pliers, keeping your fingers/knuckles a lot happier. I used a open end wrench and a pair of vise grips to turn it

I used a c clamp
