Xc60 brake calipers (2015)

Big SSS · Apr 25th, 2024, 16:57

My wifes XC60 R Design brakes felt a bit spongy so i decided to bleed them, they aren't in the best condition (corrosion) but the pads are nearly new. I bled all the brakes but when i got to the last one (front drivers) the bleed nipple snapped. I soaked them all in WD40 before hand and applied some heat to the caliper and they all bled ok except the last. I couldn't get the nipple out with an extractor either and as the calipers were badly corroded i ordered two good corrosion free (relatively) from a 2014 XC60. When they arrived i noticed the replacement calipers are two pot where mine are single piston. The replacement has a bigger footprint and being two pot calipers i thought they'd be an upgrade as they are the same fitment. I stripped them down and cleaned and wire brushed for painting and bought stainless braded hoses and stainless bleed nipples for all 4 calipers. The front right bleed nipple sheared off on the new one despite the lubrication and heat

Is it worth trying to get it drilled out and maybe oversized bleed nipples or are the original calipers better anyway? Why did volvo change from two piston to one anyway?
