1992 PA dragging front passenger/right side brake/caliper

"disable traction you should pull the two maxi fuses under hood for pump and valve and then the 3-4 fuses iirc in the fuse block."

Relay center passenger side under dash shows an unlisted #3 & 4 fuse.

Fuse block inside cabin #3 & 4. Gotcha. Except I do not see anything associated w/ABS on those fuses. Unless you are referring to the fuses under the relays inside cabin over on passenger side up inside the dash that also contains the fuel pump relay. See diagram above



The fusebox diagram I found shows #13 & 19 as antilock fuses. See above.


Under hood maxi-fuse 1 & 2 + #5? See above.
These diagrams are supposed to be for a 92 PA though Ultra. I figured the same on non-SC model as mine. I've checked the fuel pump relay under the dash on the passenger side.

Well, I've been notified they lied about brake hose delivery today. No mention when just not today.

So, I guess I'll pull the fuses once the temp climbs above freezing and see if anything changes.

ETA II: Fuses
Looking from the front of the auto the second set of 8 maxi fuses #1 ORN 40A & #2 LT GRN state ABS. My #5 RED 50A, as shown in the diagram I posted shows DR LK -next line-MISC-next line LGT. Since mine, unlike the alleged 92 Ultra, doesn't have an ABS sticker on #5 I'll leave it in.

My fuse block drivers side under dash that flips down has 2 metal box circuit breakers of 30A in fuse #3 & #4. I'll pull them ignoring the diagram I posted showing #13 20A & #19 10A being anti lock also ignoring 3 & 4 fuse on the bottom of the relay fuse box over on the passenger side under the dash.

Sorry for the confusion. I guess what I posted that was supposed to be for a 92 ultra is not the same as my basic 92PA

Again, eliminate the simple stuff first, then if no resolution, the less likely causes. The ABS/Traction Control motor is hard to miss in my car. It emits a very loud buzz when it is operating.

Not if his TC cranked the brake on and then doesnt let off while not increasing either since it doesnt see a reduction in wheel speed it wants to because of the known-1992 park avenue thing I just pointed out

AGAIN, Eliminate the easiest thing. Pull 2 maxi fuses(the fuses themselves prob dont need to be pulled since they prob are fed by those two) And then if the problem continues or isnt fixed, then instantly it can be known to be a hydraulic or fitment issue.


also i just googled some bit this may be helpful to the OP in the future:
8f757fc24955021a381d16952cfea5c4.webp
also: there is a filter in the reservoir on the abs pump thing
also: there are proportioning valves that go to the rear wheels, if you had brake lines done I hope you replaced those(not related to current issue)
 
I yanked the two maxi fuses, 4 & 5 circuit breakers & 15 & 19 fuses.

I made those short laps on both sides of the house w/o incident hardly using the brakes. I'm rolling through stop signs like a golf cart in a gated community.

Then I start using the brakes more. I'm making a conscience effort to ease into the pedal and apply more if needed. I'm also shifting into neutral as well. After a firm stop the brakes grab, yet when I accelerate they clear themselves.

I made a six mile round trip for petrol and then took me dear auld mum for a ten mile ride. Stopped on the way buying two of each: bread, bacon, peanut butter & strawberry jelly.

That did not fix the auto though it seems to allowed me enough elbow room to prevent either the brake line or caliper from locking me up. Perhaps the disc is warped contributing to the issue.

I'll leave the two maxi-fuses out for a while, knock on wood/don't look a gift horse in the mouth, replace the others tomorrow.

I'll snag some new tread hopefully by Monday.

ETA: Thanks for the Chilton link! Even a shirt pocket isn't THAT handy ...

this is a necessary option as 92 park avenue service data online is actually hard to find in complete sections

Also, op, Im glad it seems to have helped. You have a decent theory on the warping, definitely get the tires replaced and get your brake mechanical and hydraulic checked over and fixed since those issues would have probably really taxed them lol
 
I prefer book/catalogue style.

I snatched the ugly smells as a whole fried turkey cookout under the eaves gone awry el budgeto outside cover burnt offering christened scroll.

Thanks for the lead!

If the smell is too offensive I'll exorcise w/vintage bottle of Hai Karate

Thank you BGFM for all of your assistance. I had a rotor come in today. I will change the hoses, but first I want to change out the rotor and those new pads. Since the cage came off one pad they will warranty them, but I have to bring both sides back.

I found my 3/8" allen wrench, so I guess it's worth the trouble.

you should replace this just because cheap and easy"

It was a tight fit, so I spit on the fitting and made judicious use of a four foot section of 2x4 to drive home me point. An ounce of prevention plus I'll have the original as a spare.

When I popped off the old 90* the poof of air from the booster was proof enough that the system was under pressure, and fully functional, whilst the engine was off.

Being under pressure sitting there doesn't seem normal. I replaced all the fuses save the two anti-lock maxi-fuses in the engine bay.

And as luck would have it, my luck, the starter went out. I'm just like the Morton's salt girl, 'when it rains it pours'. My tools are scattered would you know the head size, 9/16"?, of the two starter bolts by chance?

Since the service manual will be a while might you have some info/diagram of the starter? Merely laying in front peeking under I see the starter & solenoid.

It looks as if the front starter bolt goes straight up.

So, before the starter lays down on me I order a set of tires that are due at ye olde tire shop the thirteenth. I plan to take the starter off before the new one arrives which if I'm lucky will be the twelfth.

Any help would be appreciated before I jack up the right front for the grand view.

The starter bolts are going to be metric...

think about 13-15mm im guessing based on GM trends
