Front brake question, HVAC question.....

[zomeizter]

That looks like the pedal linkage, the rod I speak of can be removed/adjusted after taking the brake MC off the booster studs, unless this is not adjustable on MJs? Even though you have a gap or some play at the pedal, this cannot solve your issue. I experienced this on an all disc swap I did to my 68 Travelall, but because all the components installed were from an assortment of vehicle brands, almost everything had to be adjusted/modded for proper performance.

I removed the clip so I could see to make the video, and there is no bushing that goes there. It's suppose to fit snug.

 Strange, mine has a bushing in there. Maybe mine was worn out and the bushing was added by a previous owner.

One other possibility. If the previous owner got the wrong calipers, they may be hanging up. There were some changes within the MJ years, and you can't mix and match from one year to another without knowing what parts work with what other parts.

 

I STILL have occasional issues with sticking front brakes.  Aggravating.  I put all new parts on last year.  I wonder now if I got supplied some wrong parts.  At Autozone's website, I compared 1989 MJ caliper and pad parts numbers to 1987 and 1990.  1987 & 1989 have same part numbers.  1990 does not.  

 

I'm really wondering if a store clerk maybe gave me a 1990+ part which is causing my sticking issues.    Not knowing which part numbers I used last year (I bought the calipers from Bumper-to-bumper and my pads from Advance Auto), I may need to drop $90+ to start over.  I'm sure my sticking pads are probably pretty close to needing replacement anyhow.

 

BTW, both different caliper parts state "Bleeder screw must be installed towards top".

Correct on the change between 1989 and 1990, but it's not just the calipers. There are several permutations and combinations that all have to match up. The floowing is from the book I started to write several years ago. It is copyrighted, and by posting it here I do NOT grant permission for anyone to reproduce it or to distribute it.

In general, the parts to be concerned with in keeping the front brakes compatible are the steering knuckles, the hub/bearing assemblies, the rotors, and the calipers. (There is a more complete enumeration of the interrelationship of these parts in Chapter 6, Axles.)

1.  Only two steering knuckle designs were used: 1984 through 1989, and 1990 through 2001. Left and right side knuckles are different part numbers within each group.

2.  Three different hub/bearing units were used. The hub/bearing units are the same for both sides of the vehicle. The different years for hub/bearing assemblies were: 1984 through 1989; 1990 through mid-1999 (composite rotors); and late-1999 through 2001 (cast rotors).

3.  Three rotor types were used: 1984 through 1989; 1990 through mid-1999 (composite); and late-1999 through 2001 (cast).

4.  Only two caliper types were used: 1984 through 1989, and 1990 through 2001. Left and right side calipers are different part numbers within each group.

Are you ever going to finish it?

What Don said.

 

It's like watching the same movie preview with caption "coming soon."

To be honest, I very likely won't ever finish it. Too many things have gone wrong in life since the project began. But it's still a possibility, which is why I'm not releasing any excerpts I share into the public domain.
