Brake caliper binding/sticking after hard braking

I think it's a T5Loo

Volvoloo is more fun to say. Or maybe T5 Volvoloo. Later photos appear to confirm it was not the Transporter.

Thanks for all the photos. I hope to never see that much snow again in person.

That is just crazy, I new you were supposed to get a sever winter storm , but I never imagined that!! We sure could use that snow out here in CO. I really appreciate all the help and the offer for a pump. Just let me know whenever you get a chance to dig it out. Looks like maybe early January, haha

Got your PM, and nature came and dumped 2-3 inches of rain and 60F to clear my shed, will dig for parts today


Weather change in one day!!

The soft brake hoses can collapse internally with no outward indication. Have the soft hoses been replaced? From my mechanic, I understand that hydraulic pressure applied by stepping on the brake pedal is sufficient to apply braking force, but there is no corresponding pressure to release the brakes. In essence, the lines swell shut behind the fluid after it passes through on braking. I have had this happen on front soft brake hoses that were probably original to a MY '99.

Found mine

Also saw a Cooper's hawk and the rare spotted vice Grip feeding her little wrenches some nuts

Yes, the hose was replaced. I used the wrong terminology in my original post. I said I replaced the line, when I ment the hose from caliper to hard line.

This is a real mystery then. My money's on blocked line.

UPDATE--
It was the return line piston in the abs block that was seized.
Replaced the pump and block, because they are a unit, bleed the brakes and everything is back to normal.

Thank you to everyone who helped diagnose the problem.
Big thanks to Abscate. The amount of time you put into helping a stranger based solely on having the same interest in a car, is one of the reasons I still enjoy owning an older Volvo. The community is one of the best out there.

Awwww shucks....

I’ve got six young women and one ageless Goddess wrapped in Volvo steel on the road of life, and I couldn’t afford it in either cash or time without the help of this forum. And A T5M to boot. In Nautic Blue.
