3046moparcoupe Posted February 21, 2017 Report Posted February 21, 2017 (edited) Not sure if all the linkage parts connection the brake pedal to the master cylinder are assembled correctly the way I have them here. In looking at the diagram found on pg:36 of the P15 Passenger car parts list manual, (pic #2 attached) it shows part #47 (pin) which is the connecting bolt and it appears to be coming in from the left side of the pedal (as I have it positioned here in pics 1 and 3, then the brake pedal return spring clip appears to go on to the pin next between the head of the pin bolt and the actuator rod eye bolt, then through the pedal shaft itself, (that's all that's shown on the diagram), ..next I have a washer then the castle nut..( cotter pin required but not shown ). I took this apart 4-5 months ago, and it was so basic at the time, I thought no need for a pic or sketch,....WRONG !! of course now I can't remember squat....( so before finding the diagram I was trying to insert the bolt from the opposite direction).. So in reference to the diagram shown in pic #2. the parts look to go together as I have them laid out in pic #3.... I do know that when I took this apart there was only a single washer, and now I'm guessing where it was. No washers are shown on the diagram (but they also don't show the castle nut either, course in the picture those parts would be hid behind the pedal shaft itself..... pg:32 of the P15 parts list manual does show the following parts in the master cylinder brake push rod section: 1ea push rod, 1 ea push rod end, 1ea push rod pin/bolt, 1ea hex nut, 1ea WASHER, and 1ea cotter pin.....so it sounds like a single washer is correct for this...and having it located underneath the nut would make the most sense to me. If anyone out there know's for sure or can possible take a look for me to confirm if this layout is correct...It would be most appreciated... Thank you.

3046moparcoupe Posted February 21, 2017 Author Report Posted February 21, 2017 I found this picture here on the forum, from a post back a few years. Brake pedal assy seems to be identical to mine, and the pic shows the parts going together with the spring clip (oval piece with hole in it for spring to attach to) located on the opposite side of the pedal shaft base, than where I had thought it went. Also, (unless I'm not seeing the forest for the trees here .. that would mean that the parts diagram in the pic I posted on the initial post here, is not correct. Sorta make sense as to why that oval shaped lip is found on the lower half of the pedal shaft base, as I'm thinking the spring clip needs to rest against that ridge/lip to do it's job with the return spring. see attached pic thxs Steve Quote
Chazz 47 Posted February 21, 2017 Report Posted February 21, 2017 Here is a picture of mine. I just removed the assembly this weekend 1 Quote
3046moparcoupe Posted February 21, 2017 Author Report Posted February 21, 2017 Thxs Chazz for sending the pic my wayt. I wish I could say it helps to confirm, but unfortunately it adds to the mystery..:) best as I can tell, on yours - the spring clip is sandwiched in between the actuator rod and the pedal shaft base itself, which would mean that we now have an example of it being installed 3 different ways..over the years I guess many things can happen, and obviously I'm not the only one experiencing a bit of difficulty in determining which assembly order is correct. More importantly though - you went the extra to try and help a forum member . I appreciate It and your time. if and when I find out for sure I'll let folks know. Not trying to make a mountain out of a molehill. I expect it would work to some degree assembled any one of the 3ea ways, but it sure would be nice to get it put together correctly. also - sorry folks, I didn't realize that when I Steve downloaded the picture in the last post, it would remain so small it is basically useless, the original phot was large enough to tell whats going on. I'll see if I can get the pic enlarged. Steve Quote
3046moparcoupe Posted February 21, 2017 Author Report Posted February 21, 2017 (edited) trying to get this image to enlarge. test run #1 yeah it appears to have worked. Chazz47 take a look at this picture, see how the spring clip (oval part wit the little hole in it) is located on the opposite side of the brake pedal shaft. Does your brake pedal shaft, where the nut and cotter pin are located at, have a lip or ridge that stick out about half way around the casting where the bolt goes through the shaft ? If so, I think that ridge is supposed to hold the spring clip in place. maybe this will help you as well. Steve Edited February 21, 2017 by 3046moparcoupe Quote
Don Coatney Posted February 21, 2017 Report Posted February 21, 2017 Scroll through all the photos in my Photobucket brake album. You may find or not find something helpful. Included in this album are install photos of a dual chamber master cylinder. http://smg.photobucket.com/user/DonCoatney/library/Brakes?sort=3&page=1 2 Quote
3046moparcoupe Posted February 21, 2017 Author Report Posted February 21, 2017 Thanks Don, that really helped...on pg 2 of your photobucket brake album link above, the 15th photo, shows your setup in the more stock configuration, which shows the spring clip resting on the right hand side of the pedal shaft (just like the enlarged photo I attached above with the red and green arrows), again this method also explains a use for the curved lip/ridge found on the edge of the pedal shaft, which acts as a stopping post for the spring clip. Chazz47, if you click on the attachment Don provided and go to pg-2 pic#15, you'll see what I'm trying to describe. In respect to these two photos, you might want to look at moving your spring clip to the other side, especially if the base of your pedal shaft has the curved ridge in place that encircles about 1/2 way around the casting. Don, I was looking at some pics of your blue car, you had the vintique wheels on, were those 14 or 15' wheels ? Thank you.

Chazz 47 Posted February 21, 2017 Report Posted February 21, 2017 (edited) I seen what you are talking about Steve. I will have to remember this when I take mine apart. I'm waiting to disassemble it until I'm ready to sandblast the pedals. Edited February 21, 2017 by Chazz 47 Quote
