Brake caliper won't release. Changed the hydraulic line leading to the caliper thinking it was a collapsed line turns out we have caliper issues. My question is do the casting numbers on the caliper have any relevance to finding a new one when I make my rounds and start calling rv/diesel repair shops? I added a picture below of the caliper and the numbers I can make out are 4153222 on the middle. q0241 on one side and 13 on the other. What's going to be the simplest way for me to translate to locate a replacement caliper? Thanks in advance.

I've done a bit more digging and i think it might be a bendix 4153222 73mm dual piston but wondering if there is a way to confirm that based off the picture. If not I'll rip it off and drive around the city until I can find one. Im Located in San antonio

Most good brake shops should be able to rebuild it for you. Most likely the slides are stuck.

Bendix bought haldex. They are 1/3 to 1/4 the price under the haldex name. Made in Sweden iirc. Most likely what is on your coach.

Just in case ,check out if your bendix brakes were under recall. Phenolic pistons were to blame and swelled due to moisture.
Sorry I'm on phone app search results here get all messed up on it.
Besides that most dragging due to issues are due to the pin/blots.

4153222 is the number you need. You can put that number into google and get tons of info. I bought my new calipers at NAPA. I bought calipers with all metal pistons. Some of the calipers came with pistons that had a phenolic coating. The phenolic coating swells when exposeed to water and can cause sticking.

For RVs that are not driven regularly, it is a good idea to change your brake fluid every 2 years.

I believe this is the part I ordered - https://www.napaonline.com/en/p/CALSE8609
