newly painted calipers....new problem also

[sirenformula350]

I just recently painted my calipers and love the new look.




My problem is I took all of the calipers off to paint them. After I put them back on and bled the brakes, the brake pedal goes a lot farther down before the brakes engage. It still has pretty good stopping power but I don't like the new feel. Is my master cylinder going out or what is wrong? Any help will be much appreciated.

Oh and by the way I know for sure there is no air in the lines so that is not an issue.

Sounds like you still have air. Even though you bled till you got straight fluid, there may have been another air bubble along the line that didn't work itself all the way down to the bleeder. Did you use a vacuum bleeder or a person pushing on the pedal, because most vacuum bleeders don't get all the air out. Best way is the old fashioned way. Open bleeder, pushdown, close bleeder, let up, pump a few times, repeat. This method works best for me most of the time

[sirenformula350]

yeah thats the same method i used. oh well i guess i'll have to bleed them again. Its weird because I bled them like crazy and all i keep getting is fluid. Is it possible though that the master clyinder is going out?

Sounds like air in the lines.

What did you use to compress the master cylinder back when you removed the pads?

[jimmy77611]

Anything is possible, but if it wasn't doing it before, then I wouldn't think that it is bad. The pedal going down too far is an symptom of air in the system.

Wait what? are you talking about the caliper piston?

[jimmy77611]

I think he meant the caliper piston

[sirenformula350]

I didn't change the pads so i didn't have to compress the caliper piston.

[1TA LS1]

my bad....the piston...

I think it's just air in the lines. Unless you have a leak somewhere.

I don't think it's the master cylinder....If it wasn't bad before, then it's probably fine...

I say, replace the fluid and bleed the brakes again....

I am going to paint mine very soon too...I have to change the pads anyway and might throw on some new rotors.... We'll see once I get the wheels off...

[sirenformula350]

Yeah its a nice look I like it a lot. Its just frustrating when things don't go perfectly. Well, I guess I am going to just keep bleeding the brakes and hope it gets better.

[jimmy77611]

Did you do all 4 or just the front?

[sirenformula350]

I did all of them. why do you ask?

[jimmy77611]

Just wondering. Maybe the air is in the rear. The fluid has to travel a long way. You may try bleeding just the rear first and see if that fixes it.

[sirenformula350]

yeah. The front I think are fine its gotta be the rear.

[Y2KPewterSS]

Did you start with the passenger rear first, the driver rear next, the passenger front and then the driver front. You are supposed to bleed the furtherest line from the master first the next furtherest and so on. Otherwise, you won't get all the air out. I agree like the others said, your master cylinder is probably fine, just air still in the lines.

[jimmy77611]

You can bleed the rear alone. Just go right rear and then left rear.

[sirenformula350]

yeah I bled them in that order. It just seemed like i bled them enough but I guess not.

[Silver Streak]

Make sure the bleaders are tight... had a leak in mine (somehow one of the shops crossthreaded one.. and didn't tell me... ended up getting really bad and I had a bunch of fluid all over...

[sirenformula350]

I looked for leaks and didn't see any. but its worth looking at again. I'll do that when I am bleeding them again tonight.

Looks awesome Siren, but as far as the TA on them, is that a sticker? And if so, is it some form of a heat sticker? And how do they still look? I'd like to do that to mine too but it's finding a hi heat sticker to put on em.
