MC bracket pics for Jeff

Jeff asked for a couple more pictures of the MC bracket on Lulu. The first two below are the stock bracket. It's hard to get the orientation right b/c it's hard to take pictures under there.

#3, 4, and 5 are of the mount that I fabbed for the flatfender, which had the "pass-through" bolts for a single res. MC. It's just a piece of heavy angle iron, probably 3/16", with a hole cut in the center for the bore of the MC to sit in. I also cut and re-used the "stiffener" for the pedal cross shaft. You can see the bolt for it on the lower right of the MC bracket. Originally, I though the bracket might flex under the pressure of the brake pedal, but it has worked fine without a gusset for the past 5 years or so. The other leg of the angle is to the rear of the MC, sitting inside the framerail and welded top and bottom. IIRC, I had to grind a small section of the angle to clear a rivet for the pedal cross shaft retainer thingy. YMMV

Hope this helps!

 

did you need to shorten the push rod?

 

Tim - nice setup. Kinda wished I'd seen the pics a couple of weeks ago before replacing M/C with old style .
Questions:
1. What year/make M/C did you use?
2. Is it for disc/drums or drum/drum?
3. Is it difficult to service the M/C (add fluid)?
4. Does the front reservoir serve the front brakes or rear?
5. Did you mount the aft end of the M/C at the original location or did you have to move it up or back along the frame rail.
Thanks,

 

i don't exactly know what tim did to get his master cylinder in there, but i've done the same swapusing the stock brackets...

1) the make of master cylinder can be a 76 cj, but that has ports exiting into the frame. a mid 70's ford f150 cylinder s the same but with ports exiting away rom the frame.
2) the last three pics are a disc/drum master cylinder
3) adding fluid in the v6 version can e done with a long funnel or removing the access panel. it's not to dificult, but if tim's is like mine getting the top off could be a little hectic. (moreso in my 67... the engine seems tosit about a half inch further towards the mc than my 71??)
4) larger resevoir is for the discs, the resevoir closer to the pedal feedsthe front
5) using the stock bracket i cut a the lower flange where the pedal rotates and moved the bracket up so that the back holes sat here the front hoes initially sat. the bracket has to be moved up to get the mc to sit flush with the frame rail due to the steering box. if you've gone saginaw you "should" be able to use the stock location.

i'm sure tim will let you what he did, but i'd be surprised if he kept the ross box on the flatty.

 

Great pics Tim!!! Thanks
Gonna start stock piling parts for that mod!!
I'll have to check to see how much room I have left in that area- PTO shaft is kinda hogging that area.

Chris is correct on the MC in the bottom pics - it's from a 70's F150 for disc/drum. The top two pics are of Lulu, and that MC came from a 72-75 CJ5. It's for drum/drum and has the lines entering on the opposite side as the frame rail, like we'd need. Only problem is that the stock pushrod is too short for that MC. I cut mine and welded a piece into it to make it long enough. I discovered that no one carried "generalized" pushrods for sale. I intended to just find one that was the right length and use it. Most places told me that if they had them, they came with the MC and they couldn't sell them seperate. YMMV.

On the flattie (bottom pics) I moved the aft end of the MC just a little, but I can't remember exactly how much or exactly which way. What I did was eyeball the brake pedal arm and moved things around until it matched the same "plane" as the clutch pedal. I knew that the clutch pedal was right, and would fit under the body the way it was suppose to. You can see in the first two pictures that, as the body sits on the frame, the pedals come up and *almost* touch the body. With this in mind, I didn't have to alter the pushrod on the flattie.

Like Chris also said - filling the MC is a little work, on either Jeep. I usually cut the bottom off a 20 oz. water bottle and use it for a funnel. I remove the label, so I can look through the bottle and see when the MC is almost full. Works pretty well, especially if you lay a flashlight on top of the underseat gas tank, pointing it into the access panel for the MC.

The flattie has power steering, so there was no steering box to deal with in the area of the MC.

Hope this helps!

 

Chris & Tim - I appreciate the answers and pics. Looks like a future project.
