Ford Brakes/Suspension :: 1953 F100 - New Master Cylinder - No Pedal At All?
Mar 29, 2017
I have a '53 Ford F100. I have a PB conversion kit on it. The master cylinder & Booster are under the floor. I have used this setup for many years. Recently my master cylinder went bad. I replaced it with the same model. I bench bled it, and installed it. I also added a remote fill kit, since it's difficult to check & fill. Because of the booster, the master cylinder no longer sits under the hatch in the floor.
I got everything installed & connected, then bled all 4 wheels using a bleeder kit with an electric vacuum pump. The fluid runs clear & no bubbles, but I can't get a pedal by pumping. I have no leaks. I tried with the engine off, and running. I have felt soft pedals before, but I have no pedal at all, it just goes to the floor.

1987 F-350 460 Auto Trans. Brake Pedal slowly going to the floor. Stopped at a red light yesterday on a slight down hill and I noticed the brake pedal slowly going to the floor. I had to put the truck in Park to avoid bumping into the car in front of me. I checked brake fluid level and still at the full level, check rims for brake fluid leak from brake cylinder, none. Could my master cyclinder need rebuilding or is my vacume diaphragm going. Not sure thats what its called.

2001 F-350 / 7.3L / 147K ... What are some symptoms of the master cylinder going out? And is there a such thing as a rebuild kit anymore? The pedal has been getting spongier & spongier over the past months. Truck still stops O.K. but you have to brake earlier than I used to. Pedal can go almost to the floor. Pedal continues to go to floor as pressure is applied. Does not go to floor though.

Why the brake lines have 2 or 3 coils in them near the master cylinder? Makes it a real pain to work on anything down in that area. Always snags ratchets and stuff...
My brother and I were discussing it the other nite, and the conclusion we came up with was, the first guy ever who was installing a brake system had tubing that was a couple feet too long, and couldn't find a tubing cutter, so he coiled them up.
Then the next guy saw that and figured "hmm, so THAT'S how it's done", and so on... Kinda like the story about the lady who always cut off both ends of her ham before she put it in the broiler..

I replaced the master cylinder 2 months ago and now every now and then the rear lock up for a second. its only happened a couple of times. Pulled the wheels and everything is in place with nominal wear with clean drums and rotors. Am at a loss as to why this is happening.

I have a new 12 volt wiring harness in my 1953 f100. I had no problems with the truck running until recently. Here is what is happening. The engine will turn over just fine, but not crank. I am getting spark at the plugs. My ignition switch is new. Plugs are new. I have breakerless system in my distributor. I am wandering if it could be the voltage regulator causing this. Very frustrating.

I'm about to dropkick my oil gauge but need to make sure that it is the problem. It WAS working but recently stopped. Here's what I have:
Dolphin electric oil gauge as part of their 6 gauge kit...fairly new oil sending unit (it's been on a year or so but the truck is not road worthy yet)....312 V8 and all of this is in a '53 F100.
I have verified, by hooking up a direct oil pressure gauge, that there is oil pressure. I have checked my wiring (it is all new from about a year ago) and it is all hooked up. My question is with the oil gauge removed, how can I hook up power to it and see if it works?
I could just go replace the sending unit but being that it is new I'm not going to throw parts at it just yet.

1981 f100 2wd 4.9 L6 c6 9" rear w/ front discs and rear drums. went through and fixed all leaks after I got it running. Then I got to steering and suspension. Replaced all tie rods. only thing i reused were adjusting sleeves. Taped off thread protrusion on oem steering parts so i could measure and get the new rod ends in the ballpark. Did a simple shadetree toe adjustment so i could drive it to get it aligned. I should mention i already replaced front rotors and bearings as well. Mic'd the spindles so they're in spec.
I am however running used tires but they balanced out pretty well. all torque application was strictly adhered to by the maintenance manual. made sure tire pressures were up to snuff and greased everything that could be lubed to include kingpins. the kingpins are the only thing i have not rebuilt....but i did check the radial and axial play....nothing out of spec. So I took the truck in for alignment. picked it up and it pulls to the right just as bad as it did when i drove it to the shop. the tech tried to tell me it was just a bad tire and that i needed a new one....of course i knew that was wrong.
Swapped tires from side to side, and magically the truck still pulled to the right. So I've narrowed it down to either the steering box maybe, or just a shade tree alignment tech that doesn't know his fourth point of contact from his elbow. It does not have a steering stabilizer installed, but i would think that shouldn't matter?

I would like to add power steering to the truck. What I need to do and what parts are required. Could a 65F100 come from the factory with power steering?

I have a '58 F-100 4x4 with the Spicer model 24 divorced transfercase. The front end is out of a '64/'65 F-100.
It looks to me like the front axle has shifted forward and is tilted down. The shock mount are not even close to lining up in a manner that would allow shocks to be attached. It also looks to me like someone removed a leaf from both sides.
I already know the steering box needs to be rebuilt. What else is wrong....and how do I fix it?

I'm attempting to replace the steering coupling in my 1969 f100 2 wheel drive 240 6 cyl.. I have found that the lower column shaft bearing needs to be replaced also. My problem is that I cannot figure out how to get the shaft coupling flange off the shaft in order to remove the bearing. Also if I do get it off how do I remove the old bearing?

I have a 88 ranger supercab 2.9l 4x4 with the fm146 trans and recently I have had a problem with my clutch master cylinder rod falling off my clutch pedal. I bought the new bushing and put it on and it was fine until yesterday. It wants to keep coming off. Is there a clip of some sort to hold it on or no. I looked at a few at the salvage yard and they did not have a clip just the bushing. So what do I do?

I have a 2004 Ford Expedition and today on the freeway I had to step on the brakes pretty hard to avoid an accident. After pressing, the pedal resistance became really soft and the brakes worked, but were very sensitive (a lot of pedal movement to brake). I had this happen some time ago and I did a complete system flush and no problems since then, but it has to do with how hard I hit the brakes. What could be wrong????? BTW - I never noticed the anti-lock brake pedal pulse at all during this event. I'm not even sure it is working at this point. No dash lights to indicate an error of any sort.

I have a 97 F250 that is having reoccurring brake issues, It has an intermittent hard pedal with little to no brakes when it occurs. It will stop but you are standing on the pedal with both feet. I have replaced the booster, master cylinder, and the vacuum pump in the past trying to isolate the issue and still had the problem. On this year model the abs ids only on the rear correct???? if it is shouldn't it only be affecting the rear brakes? Since this truck has a dual reservoir MC the front should still work?

If this was my car or older truck I would know what the deal was. First hill I came down in my recently bought 2003 F250 the pedal pulsed a bit as I tried to slow down...is this the way ABS brakes behave? Never had them on a truck before...she stopped ok but don't know if they are warped or normal ...I'll pull wheels later (not a daily driver)...

After putting my Ford Ranger in park and pressing down on the E-break to get the news-paper or mail. I've noticed that there is a consistent squeaking coming from the back drum brakes when the brake pedal is applied. But only for a certain period of time; then the squeaking stops.
