Brake Line Overhaul Woes...

Thanks for reading, all help is appreciated,

I have a 1986 s10 2.5 2wd long box reg cab-- Great shape overall, undercoated every year with only 145k KM.

(I amusually on this site for my 1971 Blazer - the S10 is the daily driver!)

After loaning to a friend and him popping a rear hard brake line (the long main on -- a couple of pn holes where it rubbed the bracket), I did a check of all the suspension and brake parts to see what was up, and if anything else required work. What I found was that the front brake hoses were cracked and degrading, and the upper ball joints were done (loose ish with torn boots)

So I dive in, changed out a section of the rear line no prob, changed out the upper ball joints no prob(even flared my own line etc).....All is well except the following:

1) Rear passenger bleeder rusted shut, and after much finessing I still ended up stripping it: So I will replace the cylinders out back (they are cheap, and it wont hurt anything).

2) Because of the rust/corrosion on the bracket I cannot see how the front brake HOSE connects to the bracket where it meets the hard line just beside the upper control arm. Is there a nut here? Or just a Clip? If so : where can I get them? they did not come with the new hoses,

3) Lastly, after all this, changing most of the lines etc. Will I have to bleed the Master Cylinder? (if so, can this be done 'on vehicle)

Thanks a lot for the assistance,

Jon

IMHO you should be OK to leave the master on the truck, just be sure to keep plenty of fluid in it while bleeding the system and not introduce air from the reservoir.
