91 s10 blazer 2wd 4.3 liter z.new front pads calipers rotors on both sides. the rear has new shoes. lines were bled in proper order. i re-replaced my front pads and now the brake pedal falls all the way to the floor but not without some resistance. it will hold but i can continue to push it down. i noticed a pull of fluid under the drivers sid this morning. also my fluid level was low 2 days ago. i am thinking it is the master cylinder but never experience this problem

 

brake hoses ok?
No leaks from the copper seals that connect the hose to the caliper?
Could be the master cylinder,but its like 15 bucks for a reman one,id replace it anyways.

 

i am gonna check the hose connecting to the caliper since thus didnt start until i changed the drivers side caliper. i hope its something simple. dont want to have to bleed these brakes again.

 

i spent the last 2 weeks tracing my lines for cracks or anything out of the ordinary. on tuesday i finally found the problem! on the hard line going to the rear theres a spot just below the drivers seat where the line was flopping against the body. there is a small crack there but it spraying fluid out.
how can i repair this line? can i go down to a brake shop and have them fix it or make me a new one? thanks

 

The cheapest route to go is to cut the line off back where it is good on either side of the break. Flare the ends of the line and splice in a new section of line.

 

That's what I had thought about doin. Just wasn't sure

 

well i went a different route. i went to pick n pull and got the entire section of line front to rear for $5 plus $2 entry fee. which was $11 dollars cheaper then a splice! i also found a 5" tach that i paid $8 for because the plastic on the front was broken. guess what I had in the garage...
score. thanks guys for all the help once again!!!!
