@Trav - THANK YOU! As soon as I read your post it was the DUH moment. Only work ONE rusted/frozen spot at a time, not both. Once all was unbolted, no brackets to add heat sink, I was able to take my small butane torch and heat the hose side a bit like
@ripcord suggested also. I didn't go crazy or long on it, basically burnt off the penetrants. It was nice and warm, quick spray with Seafoam Deep Creep (because why not I used 3 others already
). I held the flare nut basically in place with new 11mm Quinn Flare wrench from HF. Used 17mm on hose where it is normally secured in bracket and squeezed the 2 together. Barely any effort and it popped loose. I then sprayed the flare again and had to work that back and forth a bit before it loosened up and slid up hard line to clean it up.
Thank you again for teaching this old dog new tricks. I already shared the whole thing with others especially my son.
I don't know if it was the hose since they were never done (13 years/175k miles) or the caliper. I did new Raybestos Element3 front calipers/rotors/pads about 2 years/14k miles ago. I cleaned up the pads a week ago because my son was complaining of brake issue but it was intermittent and I had no issue getting pistons back in then. This time a week later the RF was stuck bad, hard to push in with clamp. When wife complained yesterday about the brake issue after a short drive I tried it and confirmed. About a 3 mile drive and at 40mph it was thumping when not pushing brake. Slow down and try to coast and car would slowly stop. I drove easy rest of the way back home. IR temp gun - Drivers side was about 250F, passenger side was 600F.
It's back together and working fine that I can tell. 2 new Duralast hoses, new Duralast Elite pads, new RF Duralast caliper and rotor. Getting parts from RA early and planning is much cheaper and convenient, oh well.
The Duralast hoses had same issue on both. The "guide/holding" L hook was about 1mm to long. I couldn't get the pin in hole and start the Banjo bolt. I didn't want to force it and break the bolt. I took Dremel with small grind stone and shaved the 1mm from the hook/pin. Fit right in nice and easy, Banjo started and threaded all the way with just fingers.
