Brake line install gone bad

Davo · Jan 19, 2008, 06:51 PM

i did the stainless steel line install and afterwards was getting little pressure to the front so therefore had very little brakes

the mech believed that the seals in the master cylinder maybe be shot as the fluid was dark in there before we started

no air in the system either

any thoughts here?
where can i purchase a MC kit?
any other mitsu vehicles might work that carry this 17/16"bore as these may not be available to me

Thanks

so you had brakes before the install. now you dont. You didnt bleed the system dry did you. If so you still have air in there. Or you have to bleed the abs system.

A normal switch over doesnt cause problems unless there is a leak, air in the system, or was bleed dry and then added fluid.

we did a line at a time
RS model with brembos so no ABS here
no leaks present

did you gravity bleed it. or do the 3 pump and hold method.

bleed inside caliper and then the outside....if you just did the outside it doesnt work...

inside caliper? talk to me on this please
we only did the bleeder u see through the rim

alan678 · Jan 19, 2008, 07:24 PM

both sides MUST be bled....

**SmikeEvo** · Jan 19, 2008, 07:28 PM

You did it wrong then...there is a bleed port on the inside of the caliper. Do that first then the outside.

Davo · Jan 19, 2008, 07:28 PM

there is bleeder on the inside too? crikey, didn't see/know that
to the top or lower of the caliper? pics maybe?

Aye THANKS ALOT, I am getting more relieved now

there are 2 bleeder nuts on top of each caliper, inside and outside- it's a PITA but you have to take all 4 wheels off and start with the caliper farthest away from master cylinder (passenger rear) and bleed each one in succession to the nearest to master cylinder (driver front)-- I made this same mistake 2 weeks ago. We had to bleed each caliper twice before the air was completely out of the system. And MAKE SURE that the SS brake lines are in the factory mounts behind the calipers, otherwise the lines will tear the CV boots and I will cost $300 and axle to fix it!

And...here you go. Pic of where the ports are and order to bleed.

In the a.m. I am gonna remove the wheel and look for it.
I am surprised I clearly didn't see this other bleeder and it was on top too
Does it look like the one on the outside?
I am gonna get some bottles of brake fluid and get to work
Does the back also have 2 bleeders like the front?
We got good pressure from the back, was just the front was lacking pressure

Thanks again guys for the help

Curt@MrLed · Jan 19, 2008, 09:05 PM

yes 2 bleeders. there on both sides of the caliper. Do the whole system over again all wheels off in the correct order. Also do the outside bleeder first, than the inside. Then move on to the next caliper.

Pump the pedal 3 times, hold, have someone crack the bleeder, close it as soon as the pedal starts to move. Dont let the pedal hit the floor. Do it until the fluid is perfect coming out of the tube. Wash fluid off of caliper asap. Expect to do this procedure at least 5 times per bleeder.

Thanks, will be doing tomorrow
We bled it good just we omitted the inner one and yes we would bleed the inner and then outer one.
Thanks again for all the assistance here.
