My question is: what keeps all the brake fluid in the system from leaking out if you disconnect the brake line? Either you've gotta crimp the line or plug the end with something, right?
I'm trying to repair a damaged piston dust seal that I discovered when replacing the pads and rotors on my 2014 Grand Touring AWD CX-5. I've read through an older how-to that was excellently written...it also seems to jive with other internet resources I've read:
https://www.mazdas247.com/forum/sho...o-Replace-Front-Caliper-Dust-and-Piston-Seals
I'm also referencing my FSM, but it's really not terribly useful for a first-timer to this job. My understanding is that you basically remove the caliper from the vehicle and use compressed air to force the piston out (gently as possible), inspect for pitting, corrosion, etc, and reinstall/lube the new seal. I am also intending to change/bleed the brake fluid in the system after performing the repair (Only one piston seal needs replacing).
Since I'm only changing the dust seal, is it possible to remove & replace while the piston is still on the caliper (leaving the fluid seal in place)? I'm thinking that getting the new seal on would be much tougher to do leaving the caliper connected. But to remove the caliper you gotta disconnect the brake line, and no video or how-to that I've read yet addresses what to do with the line that leaks fluid once you disconnect it...that's how I get to my original question. Any advice or pointers would be appreciated.
