Alright so recently i've gotten a really bad shake at 51-53 mph, then when I push the brakes it shakes worse... okay no problem warped rotor... bought 2 new rotors/pads etc... get done with the right side... caliper pistons compressed easy.... greased the pins etc...


move on to the left side.... only one piston will compress easy other piston is "stuck" so I'm assuming it's a bad caliper.... okay so I didn't want to put new pads/rotor on that side threw the old ones back on and went to put the lid on the brake reservoir and the dam fluid is greenish...? and obviously it shakes worse now...

I dont have the money atm till friday for a new caliper.. so i drove it home and I touched the caliper and it's hot so i'm assuming it's tossed


im asking why is the fluid green?

If it's a dark green, then I would assume it's dirty from degrading seals, and for some reason looks more green than black.
If it's neon green like antifreeze, then I would assume a goblin peed in your master cylinder reservoir. Seriously though, I don't know. I haven't encountered green brake fluid.
When you replace the caliper, flush the entire system. Empty out the reservoir first with a pump or turkey baster or something, so that you're pushing fresh fluid through the lines.

Did you touch the right side caliper when you got home? Brakes generate heat under normal use.

Yes, the right side that i replaced rotor/pads on wasn't hot, or if it was it was luke warm... while the left side was HOT. not too hot to touch but definitely hot

what gives it away for me is the piston.. being stuck/hard to compress

Well you can either rebuild or replace the caliper.

Then bleed the entire system with new fluid.
