Brake caliper Girling or POWER STOP

To resolve the caliper problem, the option choice is change all caliper pair with the model: caliper rear Right POWER STOP L5398 45.21mm / 328mm rotor caliper rear Left POWER STOP L5399 45.21mm / 328mm rotor this caliper match my Van...

Switching to a lightly modified 1990 Volvo 240 4-pot Girling caliper allowed me to go to vented front rotors and EBC track oriented pads!

I bought some Power Stop DE calipers/rotors at a good price from rock auto, unfortunately they powder coat them red before they rebuild them. I knew this before buying them so today I prepped and painted them black to match the rears.

Yesterday I took my E30 (325e sedan) to a brake shop...Both sides got the discs a bit warped and brake pads were uneven, so I got them resurfaced since they were still thick and new brake pads were installed. Right side got corrected and free right away but left side was still stuck even with the new brake pads. ...We discovered the caliper slider pins were bended and got them replaced but still the problem persisted. Guys at the shop told me I needed a new caliper on that side since it could be bended and that's why with the new brake pads it gets stuck since they're thicker. I already got a pair of new ones but will replace them tomorrow. Replaced both sides and now they’re working perfectly fine.

They've been on the car for 2 years and ~ 30 track hours without issue.

I’ve beat the shit outta my z36 ones and they’ve held up great.

I'm not a fan of the Girling 60 calipers due to the weight of them and also the scarcity of replacement parts (due to low production volume).

AG pads so I assumed AG calipers. Told to order Girling.

Had full set of power stop on mine. But one rear caliper got half frozen and chewed up the caliper so I went back to stock on the rears.

After getting vehicle to run under its own power once again, which is fantastic. I have no brakes. I've since gone gone in and torn down Front brakes completely, I've found right side metal line leaking. Also breaks & calibers had froze from lack of operation all these years. I'm Replacing all components for front brakes, except I'm rebuilding the girling calipers because they're practically $200 each and it cost 1/4 to rebuild the caliper.
