The brakes in my 521... upgraded

Recommended Posts

521 brakes are freakin' upgraded.  :)  Klotzified you might say... And with some other work, it's like a new truck.  Pretty happy.

 

ETA: I wanted better and more consistent braking, and less adjustment hassles from the drums.  I think DanielC says to adjust drums every oil change - or is it every gas fill?

 

Install of Mike's kit was really smooth.

I followed Phixius' model with new brake lines and MC. Moved the distrib block to the driver's side, added a proportion valve to the rear. First time bending lines - definitely not art.

Found 720 hubs at a junkyard. Pulling the old brake fittings was tough - pretty much vise-grip work. Stuck with SAE fittings then metric adapters to new stuff. It's getting complicated to figure out wrench sizes on this thing.  :rofl: While I was there replaced old tension rod and control arm bushings.  Tightened up the steering a lot.

 

"Sorry sir, we're full up now, but I can add you to the waiting list."

Nice brakes but what does this thread mean. The title is mis leading. Nice truck though

Edited title to clear up.

 

Had struggles and unwanted braking excitement with the drums over the years.  Decided to attack the problem.  I replaced most everything at one time or another, except the rounded-off nuts on the brake lines.  And got pretty good at drum adjustment (my tip: touch knuckles to compare heat at the wheels after a drive), but balance and performance were never great.  Some pulling issues were with steering slop too - from the box and bushings. Helps a lot to tighten that up.

 

Pedal can still be a little mushy/wooden if you don't adjust the rear drums. But stopping feel is a lot better, and much more predictable under hard braking.

mind if i ask how you installed the control arm bushings? i got some recently, and wasn't sure if i could cut the old ones out and push new ones in, or have a machine shop do it? 

 

My terms are probably wrong - I changed bushings #8 in the pic below, outer bushing at top of king pin.  Had done most all the other ones before, but these were torn. (Moog part for these is K9207).  These pop in/out pretty easy - no press or burning, they're squeezed by a bolt.

 

I also replaced the upper link spindles and screw bushings (#5 in pic), trying to chase the wobble in the arms - have had those parts on the shelf for awhile.  180 ft lbs for the screw bushings!  Honestly didn't improve the movement as I'd hoped.

 

You talking #6 in the pic? Manual shows a special service tool with a hammer to tap it out.  Didn't mess with it this time - can't remember the routine.

Yes four wheel disc brake shop truck is spread out a little and I am not sure the four piston calipers in front are needed to stop 2K 521 , but parts are listed and uses 240sx/maxima calipers in rear, and rear hoses drop outside near wheels ? best part is E brake ,have a vendor that can remake with a phone call from my set we already worked out .I scored a dog 86 4x4 yota for shop truck so I need to get back on DE swap 521 soon.
