hey guys im still a noob but learning so just bear with me. I removed and painted all the calipers on my car non brembo and when i first took off my old calipers i just let the brake lines open until it bled out all the fluid on each side. So I just installed the calipers and hooked up the brake lines can i add the brake fluid directly into the reservoir under the hood or will it have air bubbles in the lines ?

 

1. Bare with you.
2. What color
3. Yes.
4. You will have to bleed them
5. Bare

 

Should of painted them on the car..

 

Should have never painted stock, non BBK calipers anyway

 

Not bad if done a neutral color like grey or black. better than looking at rusted or stained calipers.



Anyway OP,

You pretty much need to bleed all 4 brakes now. Not a hard task to do, but round yourself up a buddy to press on the pedal, a couple bottles of brake fluid and a 10mm and 8mm wrench and bleed the brakes.

 

Definitely need to bleed em. As mentioned above, this is a much easier task to accomplish with two people. One to pump the brakes and the other to man the bleeder valve on each caliper. You need to be real careful when doing this to keep an eye on the brake fluid level and not it get too low. If the reservoir gets low enough to suck in air, you'll have to start all over again and rebleed the system.

Also note that you should be very careful when working with brake fluid as it is corrosive to paint and plastic and will eat rubber, so don't spill any on any painted surfaces (including your newly painted calipers) or headlight lenses, or your belts, engine seals/gaskets, or CV boots.

It's probably wise to wear some disposable gloves too.

 

If a buddy isn't around to help you, look at the Motive pump, its about $60, works great! Not a bad idea to have anyway since the fluid should be drained every year or two to prevent problems with the calipers locking up, etc.

 

If you do spill the fluid on paint, water ASAP! Brake fluid is hydroscopic so it will absorb the water and be flushed away.
