Properly adjusted 11" drums should stop that rig just fine. And keep in mind that drum brake performance (dry AND wet) can be improved by drilling the drums...
What do you mean drilling the drums & would that work on the rear drums of an XJ if works will do it on my CJ 10 also

Thx

Drilling, or venting the drums, prevents brake fade on long, dry braking (long steep downhill). It also vents water/mud, so your brakes work well immediately after a deep water crossing, no more wondering what your brakes will do when you need them..

I've had plenty of 4-wheel-disc-brake vehicles, including my current LJ.
Without a doubt, drilling my (4) 11" drums gave me braking performance equal to, or better than 4-wheel standard discs, wet and dry.

Do a search on C.H. Topping... that info, along with my wet-drum-brake experiences, led me to the conclusion that proved to be an excellent upgrade for an old Jeep that sees frequent deep water.

YMMV...
officially on the "to do" list

I never wonder how my brakes will work after they get wet, I already know they won't work worth a ...

IJump I need to go through all of the fluids and check some basic stuff. There are some minor issues that I think I can fix with some basic maintenance. It is a 30+ year old vehicle...

Drilling the drums looks like an interesting idea. It makes sense after reading about it some. I may look into that as a winter project.

First, the mushy brakes and bleeding the lines, though. Gotta make it safe so I am comfortable letting my wife drive it.

aelwero my DJ has 4 wheel drums, and once the pedal hits the point where it engages , there is almost no play in it at all. Once the brakes start engaging, I have maybe a half inch of travel left, and that half inch is the difference between slowing down and completely locked up.

The pedal travelling to the floor is usually shoe adjustment (my '71 has no self adjustors, I have to crank em by hand once or twice a year, I swiped a butter knife from the old lady and cut a u shaped notch in the end and bent it to match my jeep, works much better than an actual brake spoon). The pedal going down an extra few inches after the brakes start engaging is air in the lines you need to bleed out.

Like lynn said, drums should be plenty, but if you've never driven one, spray them all down with a hose and drive around the block to see the wet/dry difference once, because it's definitely something you need to be aware of...

never thought about drilling my drums... but it sounds like a really good idea

Rusty Knutt Bleed the lines thourghly, and adjust the slack in the shoes....I don't remember if the front drums have the self adjusters( cycle the brakes while backing up)
04-05-2012 05:52 PM
IJump Drums in the front.

The brakes feel kind of mushy to me. Gotta press the pdeal almost to the floor to get it to react. After that, it stops just fine. Is that normal? The master cylinder looks new and the PO said he replaced it. I haven't had a chance to look at anything else dealing with the brakes....

I too have a '76 CJ7. Does it have disc brakes in the front?

IJump Here is one picture.

Rusty Knutt Welcome back to the fold.

IJump It has a 304 V8 in it. I checked the frame before I bought it and it looked pretty good.

Pictures later this afternoon.

lynn Pics??

'76 was the first year of the CJ7. Check frame carefully for rust-through, and cracks near the steering box, spring hangers, shackle mounts and motor mounts.

V8 or 6 cyl?

Sounds like you've got a winner!

New to the CJ world

My wife and I decided last month that our JKU wasn't working as my family's daily driver and only "normal" vehicle. So we traded that in on a civic hybrid. My wife, being the wonderful wife that she is, said I could eventually get another Jeep as a "toy". I was sad when we left the Jeep at the lot....

Well, back when I was in Iraq, I decided that when I made it home, I would get myself a welcome home present. I did, and it was a nice little Harley Davidson motorcycle. But I didn't ride it much. Much to my wife's surprise, I decided last month to sell my "Welcome Home for the War" present I bought myself. I took the money and started looking for a Jeep. I saw a nice 48 CJ2 in my price range, but I didn't think that one was for me. If I had a 40s Jeep I would want it more original that the guy had it. I had a couple of people with CJ7s sell to other people before I could take a look at them.

Last week I found a 76 CJ7 that looked pretty good in the pictures. The guy selling it agreed to hold it for me until I got back from Chicago on Monday so I could drive down on Tuesday to look at it. I looked at it and liked it and ended up driving the CJ7 home Tuesday evening. I took my son with me (had to have someone drive the car home) and it took us 4 hours to get there and about 5 to get back. I drove from the mountains in TN back to KY on back roads and highways through some pretty nasty rain. The CJ ran beautifully the whole time. I didn't even get wet in the storm. I definitely think I upgraded when I sold the bike and got the Jeep.

So, the 76 CJ7 joins the 01 TJ that I used to drive and gave to my son when he turned 16 in our driveway. Unfortunately, it has rained every day since I got it, so I haven't taken the top off yet. I can't wait to make this Jeep my own....
