Help! Front Brakes driving me nutz

Hey all.

Tired of throwing parts at this beast.

On Friday, I noticed that the passenger front wheel brake seems to be dragging somewhat. I have a wireless temp gauge and driver's disc read 160 while passenger side was around 300.

Therefore, this weekend I replaced the caliper with a brand new reman unit after diagnosing that was the issue.. turned the bleeder screw and got a steady stream of brake fluid (no burst of fluid) and the caliper was a pain in the arse to remove so it seemed like it was seized. Took it for a spin and got back to the house.. same deal. So, I replaced the line from the wheel well to the caliper and bled the system to replace most of the fluid (it wasn't horrible to begin with but I thought I would do it anyway.

Went for a drive again after all this and seems to be slightly better drivers side was around 140 while the passenger side was around 220.

Any insight into what I should look at next?

Re: Help! Front Brakes driving me nutz

Did you replace the rubber lines at the same time?
My guess they are collapsing inside, and allowing the brakes to be held partially engaged

Yes, those are the ones I was referring to.. they're rubber from the inside of the wheel well to the brake caliper. I thought the rest of the brake lines were hard.

Re: Help! Front Brakes driving me nutz

So, new rubber brake lines, and new calipers. How did you bleed the brakes ( what method)

Do you have hydro boost, or a vacuum booster behind the master cylinder?

When I installed the caliper I gravity bled till it came out then I connected a clear line to a cup filled with brake fluid. Pumped the brakes until I didn't see any bubbles in the line. Then closed it up.

When I replaced the line I also flushed the fluid. Kept pumping the brakes till almost all the fluid was out of the reservoir (to the min line) then filled with new and pumped till the fluid coming out of the brake caliper was clear and no bubbles then closed it up.

I don't know for sure if I have a hydro-boost or not. I don't see anything that looks out of the ordinary. How would I know for sure if I have one?

I just looked up a photo of a Hydro-boost and I don't think I have one of those.

Re: Help! Front Brakes driving me nutz

since you put a remanufactured caliper on, my bet is the caliper is hanging up. i have had such bad luck with them the past few years on the 02 and 04 that i switched to brand new................and no more problems.

Thanks for the idea. The original caliper I bought was a year old and I had that one replaced under warranty. They likely won't give me my money back at this point so I might have to try another. I noticed that this one doesn't have "Ford" on it so I assume it isn't a Ford part to begin with.

This morning (after my normal commute) drivers side was 135. Passenger side was 280. It's definitely hanging up yet.

Anyone else has something I can try feel free to offer up suggestions.

Most parts places (around here anyway) will let you pay the difference to upgrade to the new! Worth a try at least
