Replacing Front Calipers

[64FRSFan]

Hoping someone can help with this one, or let me know if just doing something completely incorrectly. After 5 years of track days, one of the pistons in my front brake caliper seized up, so i bought some rebuilt ones for both sides. All i did was remove the brake lines and bracket's and re-installed, but now i can't seem to bleed them. pushing down on the brake pedal and no fluid it coming out. Very small slow flow in the back calipers, but can't get anything to come out of the fronts. Taking the calipers off initially did result in me losing a lot of fluid from the reservoir and I'm certain I have a ton of air in the lines. Any thoughts on what I may have done incorrectly or need to re-do? I can't seem to figure this out and I've rebuilt one of them in the past and I don't recall this being an issue. Do you think my master cylinder may be shot? Any help would be appreciated.

might be worth checking this out. maybe you missed a step? Sounds like you'll need to bleed them again and fill.

If you have lost most all of the fluid it is sometimes hard to get large air bubbles out. Two devices that can help are a mityvac, and a pressure bleeder. The first pushes the fluid into the system and the second pulls it in.


Using the pedal to push will compress the air making the bubbles smaller and helps move them through the system while mityvac pulls the fluid in and expands the bubbles helping them to float free of surfaces.

Guys (or Gals if its the case, I hate to assume lately) thank you soo much! Great video! I will reference for years. Plus I love the set up recommendations. God I wish I had lift. God bless the wife, she went back and out to help with the bleed and I seem to be getting some fluid out of the back passenger caliper. Kind of weird its working today and not yesterday. We had to stop, dinner time, and I don't want push my luck with the better half. Question, the banjo bolt, it doesn't need to be perfectly aligned with the hole on the bolt and hose, right? That would seem to be really poor engineering. if that's really what it is, i'd be disappointed in Japanese engineering. There was some reference to aligning the banjo, but didn't quite follow, otherwise, really informative. Thanks

There may be some corrosion on the hole in the banjo or bleeder bolt. Since you are bleeding anyway I'd just pull out the bleeder and banjo out and look at it. Keep a pick nearby to poke the hole. Put your finger over the opening to prevent excess fluid loss.

If you have issues getting help to bleed buy a motiv power bleeder. Pays for itself in one use. One of my favorite purchases and not expensive at all.

Make sure you have the right crush washers... I think I remember using what I had on hand once and facing a similar issue, though that would have been a different car...
