Yagster Posted December 14, 2013 Share Posted December 14, 2013 I just replaced my front brake rotors and pass and after I picked it up the brake pedal is really soft and goes all the way to the floor and my 88 gl wagon slowly slows down what is the problem that is making thisn happen. The mechanic said he bled the brakes. Link to comment Share on other sites More sharing options...
SmashedGlass Posted December 14, 2013 Share Posted December 14, 2013 Your mechanic bled them wrong then. Link to comment Share on other sites More sharing options...
idosubaru Posted December 14, 2013 Share Posted December 14, 2013 *** Were the brakes working perfectly prior to this? *** Why was it worked on/in the shop? 1. there is still air in the system 2. the caliper is leaking - the process of pushing the caliper pistons back in can compromise a weak or failing piston seal 3. the master cylinder is hosed #2 and #3 are highly unlikely, so assuming we know everything there is to know about the brake system on this vehicle, #1 is highly likely.

SmashedGlass Posted December 14, 2013 Share Posted December 14, 2013 And to add......what 'mechanic' would call his job complete if that is how he handed it back to you?!? Link to comment Share on other sites More sharing options...
drake13 Posted December 14, 2013 Share Posted December 14, 2013 Could have the caliper bleed valve cracked open. Link to comment Share on other sites More sharing options...
djellum Posted December 14, 2013 Share Posted December 14, 2013 subaru's bleed in a funky order, the mechanic may have just done the standard order and left some air in there. I can't remember the order and only have a few minutes but a search should turn it up. Link to comment Share on other sites More sharing options...
MilesFox Posted December 15, 2013 Share Posted December 15, 2013 He probably bled the fronts only, but the rear will need bled also as this is a dual-diagonal setup. the front and opposite side rear wheels are on the same line, and vise versa for the other line. If the car is a manual transmission, hold in the clutch while pumping so fluid moves through the hill holder. Link to comment Share on other sites More sharing options...

Yagster Posted December 16, 2013 Author Share Posted December 16, 2013 The mechanic didn't bleed the back brakes just the fronts Link to comment Share on other sites More sharing options...
idosubaru Posted December 16, 2013 Share Posted December 16, 2013 that's fine and works sometimes if you do it before all the fluid drains and you only need to push air out of the one line that was opened. it would seem that the entire system needs bled now to make sure it's done and done right.

mcmillonbe Posted January 4, 2014 Share Posted January 4, 2014 Ran into this problem awhile back, decided the bleed the brakes in the Brat since the brake fluid looked like it hadn't been changed in many years. Used one of those one man bleeders, and ended up scoring the piston in the master cylinder. Bought a reman unit off of ebay and spent a good hour bleeding the brakes. Still all the way to the floor. Finally got pissed and went over to Harbor Freight and got a brake bleeder kit that hooks up to an air compressor. Bam, still took about 45 minutes to get all the air out, but now the brakes work good for a old car. Link to comment Share on other sites More sharing options...
