 Posted: Sun Oct 27, 2013 7:19 pm Post subject: bent front backing plate - brakes |
 |
|
I started to assemble the front brakes today - upon installing the new wheel cylinder, I noticed the brake pads wouldn't sit correctly. Upon further examination, I noticed there is some separation between the 2 pieces - the entire backing plate - and the 2nd piece where the cylinder bolts to.
I can't even move it.. Any suggestions on fixing it - I really want to use this one if I can. Could I use a vice grip to bring the two parts together and bolt them or should I scrap it?

How are the brake "pads" not sitting correctly? Is the problem on both sides?
I am wondering if you might have the wrong wheel cylinders!
In yer other thread, you said you got your brake parts from Wolfsburg West, but WW lists only German w/c for the front of a '65. http://www.wolfsburgwest.com/wolfsburg_new/brakes/bug_brake/front_cylinder.cfm
If your wheel cylinders were in those "O.E." boxes, I doubt that they are German, so . . . . check the part numbers.

I did get a nice box of parts from WW today to start putting the front brakes back together. All new master cylinder, brake hoses, brake hardware kit, wheel cylinders, pads:

The backing plate is not sitting flush, thus causing the wheel cylinder to be straight, thus causing the pads to be somewhat crooked. I don't think it's the wheel cylinders, they fit fine.. when I look at both backing plates side by side, the one (above) has some separation between the 2 pieces.

| Personally, I'd try to pinch it back together by means of a vice, vice grips or a hammer. Doesn't look like it needs much tweaking to get it to where it needs to be. Good luck |

that is kindof a tough one to fix, likely the thinner backing plate is bent, however to bend it back to the right position you would need to over bend it a bit then it will spring back, however you cant over bend it without running into the thicker cylinder mounting plate.
If you can weld, maybe try to pull the two plates together with a vise grip or C-clamp then make a weld to hold the two plates together. I got a welder so that is what I'd be thinking of doing.
if you don't have a welder the thing to do is clean them up with a wire wheel in the area to tack a weld, (use some sand paper to get between teh two parts as much as you can also), then clamp them and take them to a muffler shop or local welder, they could crank that out in a minute it you have already wire wheeled, cleaned it up, and clamped it for them.
the weld(s) should be located near where the gap is large on the circumference of the round part of the thicker plate. that would be the best fix I can think of. It should be rock solid. any commercial welder shop should be able to do this for $10-$20 if you have it all prepared for them.
then take her home and re-paint it. |

You have to figure out what's bent - the large thinner piece or the smaller thick piece. To me it looks like the smaller thicker piece but that could be the photo and the angle the pic was taken. If the small thicker piece is bent then the brake cylinder will be crooked which could cause the shoes not to sit against the larger piece. Probably the best way to straighten it out would be bolting it on the spindle and give it a few gentle whacks with a small hammer.
If the thicker piece is indeed bent then clamping the two together won't do anything as the smaller piece is thicker and stronger and the thinner piece will just conform to it and the whole thing will be bent/warped.
