1988 mj So the brakes suck haha......i've bleed them to no fix.....pedal goes to the floor no matter how mant pumps with truck on or off.......no fluid leak from calipers or drums.....fluid levels are good still. hissing noise both on compressing and rebound of pedal......brakes only work and barely at that when the pedal is smashed to the floor and I'm no skinny twig by anymeans. I'm assuming the brake booster/master is bad and needs replaced?

eh, i figured it wasnt the right tank. so back to my question, why the over flow of coolant with caps firmly in place?

no sir,it has two caps....a large one and a smaller cap that has like a plastic slide attached to it underneath. could it be a different bottle yes considering half the truck is botched to heck with wires and parts. i can get a picture tomorrow

1988 mj...121k...5speed.......Before i get flammed, I'm not new to the mechanic world in any way sense or forum, but this is my first jeep and closed coolant system i've ever had the pleasure of owning. Just bought me a mj last weekend for $1000....and now i have some closed system issues. When i let it sit and idle and warm up, it starts to completely spew coolant from the bottle.....i canked down the larger cap and now it seeps out of the little cap hahaha.....yes the fan blows, all the lines get pretty hot so water pump works, A/c fan is in the works of being wired up for extra cooling(like i said it never left the driveway).......oil looks good......no coolant smell(maple syrup smell yummmm)......no leaks by the head gasket or freeze plugs. Now the coolant bottle was empty when i bought it, and yes i never refilled it yet due to the this new issue that is going on. My question is will the system not being "purped" properly and having air in the system cause this to happen? ANY help is welcome.....Please don't tell me the head gasket it done for!!!! Thank you -ED p.s. The dang jeep love has already kicked in =)
