Alright guys- Its been a while since Ive been posting, and yeah I have a f150 but I still love rangers. Anyways, my question is about brakes. How important is bleeding? Here is the story- My brakes shudder, I ask my neighbor to walk me through it. We put new pads on, one ends up in backwards. He did that side, so I'm pissed. The next day we fix it but it gouged the rotor, so now they either need to be turned or replaced(most likely). I just wondered how necessary it is to bleed the brakes, when we did the pads, we just cranked the pistons back into the caliper (which didnt seem right to me) but he and others have said its ok to do. Now, I just wasted $70 on pads, since Im told they will rewarp the new rotors if I use them again. ohh well! thanks, Ryan

If you dont bleed the brakes, most likely there are air poickets in the line, and will eventually screw it all up..

When you hit the brakes, its gonna be like trying to push fluid down a balloon, that has air in it, the fluid wont go down cause of the air.

The pistin needs the fluid, and your gonna screw up the caliper if it doesnt get it..

Just bleed the brakes, its not hard AT ALL, one screw, loosen it, then bleed, then tighten... Not hard at all..

damn, I hope my calipers arent f@#ked up. Im doing the rotors and new pads tomorrow, by myself, now with my stupid *** neighbor. i'll bleed them then. thanks

You don't actually have to bleed the system if you are only changing pads and rotors. If you changed the caliper then yeah, bleed the brakes. The system is closed, if you have air in the lines then it came from somewhere else like a broken line or a bad master cylinder.
If you do plan on bleeding the brakes, it is gonna take 2 people unless you have a hand held vacuum pump.
