brake problem
Hello all, I reworked the entire front brakes on my 1975 Ford Courier, and now have a "pulsating problem" in the pedal. Removed old brake shoes and old wheel cylinders(2 each wheel). Carefully cleaned areas very good and reinstalled new brake shoes, and new brake drums plus 2 new wheel cylinders on each wheel. Had a helper assist in bleeding the wheel cylinders right side first then left side.Kept master cylinder full with new brake fluid while doing so.Have not messed with the rear shoes,nor the centralizing pressure differencial valve.Intend to replace the rear brakes soon, like the fronts.Now I am having a severe "pulsating" through the entire truck when braking, the more so when stopping hard. Pedal is about 3/4 of the way to the floor.Am usingthe 1975 Ford Shop Manual plus 2 others doing the repairs. Please indicate to me what I am doing wrong, and perhaps where the problem is. Should I have the 2 new drums turned? Thank you for your troubles and help. Please reply to jimka2@hotmail.com. Jim S.
My2007 has been running well so have not followed this and other forums. I went in for my 55,000 mile check and change my Mobil 1 oil after a year for other service. all checked out well except for pad wear on the rear brakes. I checked and found a ridge around the edge of the disk so I guess I need both. Now the conundrum, front brakes are supposed to wear out faster so why the rear. The rear were replaced under the original new car warranty, both pads and disks.
Now as an engineer I think I know why. Reading the service manuals i find that the emergency brake engages a toothed piston in the brake caliper. When the emergency (parking) brake is applied it pushes on the tooth and screws the piston in clamping the pad against the disk. When released the piston should back off and release the pad from the disk. If this automatic adjustment does not work there is continued wear.
I did find that to retract the piston when replacing pads you have to use a special tool to screw the pad back into the caliper.
Comments please, am I correct or is there something else?
Has ford fixed this for anyone at 55,000 miles under warranty or recall. I do have an extended warranty?

I think your assessment of the problem is good. The only way to be sure if Ford will come across is to ask and you never know because where one dealer won't another will.
Does your warranty spell out what it covers and what it won't?
