Took calipers off to get powder coated...do I need to bleed my brakes?
Just like title says took the calipers off my car to get powder coated but taped off the lines so brake fluid won't leak do I still need to bleed the entire system or can I just add a little bit when I put the calipers back on?

You need to bleed the system. Not only could air have gotten into the lines, but the calipers themselves will have been drained.

All I have to do is press the brake until there is no more fluid right? |
this scares me, you need to bleed them in order to get the air out once the calipers are back on, you should get new crush washers too. you have 2 bleeders per caliper and they need to be done in order for safety. Get help if you at all not sure...

I did the same thing this past fall, after I installed my freshly powder coated calipers, I took empty water bottles and some clear vinyl hose and used 2 per caliper. I drilled a hole in the bottle caps and inserted the hose and attached the other end to each bleeder. Filled the brake reservoir and had my brother pump the brake peddle while I open one bleeder at a time until all the air bubbles were gone. It worked like a charm! Here's a link from the DYI section of this forum that might help you out. http://www.camaro5.com/forums/showth...leeding+brakes

BRAKE BLEEDING IS SOMETHING THAT CANNOT EVER BE ALLOWED TO BE DONE INCORRECTLY. I also live in NJ, so I might have a little extra personal interest in OP getting this done right and done right the first time. I'm sure that the calipers would have dribbled enough fluid out of them during the powdercoating process for good sized air bubbles to be in each of them now. Good call on replacing the crush washers. Norm |

All 3 of you guys are right. And he should listen to this info very closely. The copper washers need to be replaced. The caliper bolts also per GM. Up grade your brake fluid to Synthetic. You have to start the bleeding from the farthest point. Which is RR first LR next RF then LF in that order.
For V-8 Torque specs. Brake Caliper Bleeder Valve 89 lb. in. brake Caliper Bolt-Front [L99,LS3] 44lb.ft+90 degrees Brake Caliper Bolt-Rear [L99,LS3] 30 lb. ft.+90 Brake Hose Fitting Bolt 30 lb. ft. Hope this helps you. |
Man these answers would intimidate the heck out of me. If I was the OP haha. Brake bleeding isn't really that complicated. Just do all your research, and if still not confident get someone who has some experience at it to help you. I'm sure there is someone in New Jersey from this forum who could probably help you out as well.

thanks for all the tips it is slightly intimidating lol.....can i buy all the new bolts from my dealership? Furthermore what new brake fluid should i use?
|
At a bare minimum, DOT3 brake fluid.
But I strongly urge you to look past minimum-spec brake fluid, into whatever DOT4 fluid you can find that has a high wet boiling point (dry and wet B.P. should be listed on the container). I say wet boiling point because unless you periodically bleed or flush your brake system you'll eventually end up with fluid that's considered "wet". Do NOT get DOT5 fluid even if you see it on the parts counter shelf. The higher number does not mean that it's better. Only that it's different and should never be mixed with the DOT3 that you have in there now. Norm |
does anyone have a ling to where i can get some good Dot 4 Fluid? Should I go with the Castrol SRF Dot 4? If so can someone give me a direct link to that specific one not too sure where to get it from. Also is that good fluid where I wont have to bleed the brakes? Because since I got my car in 2010 haven't flushed my brake fluid or bled them and don't want to have to bleed them often either.
