I picked up a 1995 ls400 with 125k earlier this year. I gave the car little maintenice (new tires/all fluids changed/new brakes pads+rotors). Yesterday the brakes felt little loose. (you can press the pedal and it feels soft it goes 70% down, Today in the morning it went all the way in without stopping. So in short no brakes. Shut the car off and started again and its working fine. ?? What could be the issue? THanks

 

Sounds like your master cylinder might be singing its swan song.

 

Either that or...say, do you have a rather large life insurance policy?

'Second' on the master cylinder.

 

does the pedal pump up? are u losing fluid or is the master cylinder low on fluid? does the pedal hold for a second and then go to the floor or does it go straight to the floor? be careful if u do the brakes,make sure u know exactly what u r doing. do not turn the key to the "on" position if u r bleeding the brakes and make sure u bench bleed the m/c and bleed the system correctly after ward.personally if u r not experienced then take it to a reputible shop

 

Thank you guys, i think its the master cylinder, i got the brakes done from minekie, My buddy he has worked on most of my cars. Brake fluid is good, not sure how to check the cylinder fluid...
