Second hand bike, my first time encountering Hayes Sole brake calipers. My brakes front and back have gone a bit weak so I wanted to tighten them up a bit. Each side of caliper has an allen key section that pushes in each brake pad. When you pull the brakes(hydraulic) one pad moves in and the other is static. https://www.parktool.com/blog/repair-help/hayes-hydraulic-brake-service
Front brakes are okay, I could screw in the static side a bit while the moving side is already all the way in(it does screw out ok), brake pads look like they have a bit more life left. Braking feels ok now but maybe not super strong. :-7
Back brakes both sides are stuck, I can neither screw them in nor out. I have cleaned a bit will leave oil/WD40 (WARNING! you should lubricate using DOT brake fluid, especially do not get oil/WD40 anywhere near or on piston seals or brake pads or brake disc) soak in and start using more force tomorrow but I was wondering is this a problem someone else has encountered, does anyone have any experience and advice with regards to these brakes?
