Rebuilt the calipers, now they leak!

How difficult was it to insert the piston into the bore?

Mine was so tight I had to use a c-clamp to press them in. Some people claim they can insert the piston by hand but I could not. It was the same on the front pistons and the rear. The dust seal tears easily, on mine if I didn't get it right the first time the seal was history.

Are you sure the dealer sold you the right pistons/seals for your caliper?

Did you purchase OE seals or aftermarket?

Did you purchase OE seals or aftermarket?

Purchased everything, pistons and seals from Suzuki. Piston and bore tolerance was very tight with the seal installed.

I found that if you push or pull the pistons slightly off center they jam and the same for removing. Pressing or pulling the same piston exactly perpendicular with the caliper, then they slide in or out easily, if lubricated with a little brakefluid beforehand.

oem parts in my case.

the pistons went in easily, when lubricated with the brake fluid.

i have worked on other calipers before and could always push the pistons in by the hand (after re-asembly).

on the rear brake i reused the old selas and pistons and the pistons went in easily and the brake functions well, no leaks.

however, i still need to road-test the brakes to get the real picture.
