The back story:
Six years ago, when I aquired my 95 Volvo 850 turbo I had to have the brakes, rotors etc replaced. Two years ago, my Passenger side front Caliper siezed up and wrecked my rotors. It was Christmas and I was lucky to get in to a shop to have the rotors, calipers etc replaced. My memory is fuzy, but for $1500 I’m pretty sure they did both calipers?
Recently I drove my car 5 hours up to visit with my girlfriends’ parents for the weekend. While I was there I noticed that my drivers side front caliper was sticking.
(steering wheel was shaking though the road was smooth, when I got out, only that caliper was hot and the wheel was covered in black dust)
It was saturday night, Sunday all the shops were closed (rural area) and sunday nightI had to be home to fly for a business trip. Being on a farm, we had some heavy tools including an impact wrench. so we jacked the car up, removed the wheel, removed the brake caliper from the roter. We used a C clamp and a metal bar to compress the piston in the caliper. Then put a block of wood in, the caliper and pressed the brakes causing the piston to expand. Compress, Expand, Compress, Expand, Compress, then Reassemble. The piston was visibly rusty where I could see it, but it moved well enough under the c clamp and brake pedal.
I drove the whole way back, everything was smooth, I was getting 24+ mpg average, I stopped to check the brake temp periodically, and its fine. Now I’m on my business trip, and when I get back home in a week I’m supposed to drive 5 hours up to my family’s place right after I return. I will have 1 afternoon where I can rush the car out to a shop, which I will definitely do, I will at a minimum change/flush the brake fluid and replace the two bolts that I loosened and reused that are supposed to be single use only.
Could something be wrong with my master brake cylnder that’s causing the brakes to sieze up and wreck my rotors?
Do I necessarily need to replace my rotors ? (I think I caught this one right away and the rotors might be undamaged)
Do I necessarily need to replace both calipers ( I don’t drive much, remember, they should be less than 2 years old with at most 10,000miles on them,l more likely only 5,000)
Obviousl I will rely somewhat on the story I get from the shop I go to after they inspect, brakes are critical safety equipment and so I’ve shyed away from working on them myslef in the past, unlike engines, but I would like some learn-ed opinions on what’s absolutely required and what might be ‘fleecing’ here.
