enough shiny parts... time for some of the grimy bits!

really put this thing through its paces this weekend, and feels like money well spent now given how smooth its making this whole brake line making process! definitely wasnt cheap (and the cost per flare is pretty high ) but i dont regret it after having used it now.
also, the cunifer brake line material from fed hill is AMAZING... extremely easy to work with. highly recommended!

couple test pieces

heres the broken bit that started this madness - drivers rear suspension height control feed line

new guy, installed!

one of the new cross over lines for the rear brakes, next to the old one

both installed

were now down to just making a new passenger side rear height control feed line and were ready to go. that one is about to fail in the same manner as the one that broke, so i figured why not go ahead and replace it while doing the soft line for that circuit.

im amazed at how quickly this is all going, so im hoping to have this wrapped up in a few days. weve almost got the old pass side height control feed line out (all the damn rusted on line clamps are off, and the line is loose) it just needs to be wiggled out of the car.

then later this week id like to give everything a once over and see if we can get the damn thing to bleed (fingers crossed!)

quick update, no pics, but we fired it up last night after getting the last hard and soft line in.


everything connected to the rear accumulator bled fine, we can get clean fluid through there - this is progress! - we now have 1/2 of the front brakes working, along with everything out back!


still has issues feeding fluid to the front accumulator though, same as before. noodling through that with the RROC guys at the moment, and we'll see what the next step is.
if it means pulling the pump then so be it, but im not totally convinced yet that thats the issue - pump doesnt make noise and i can feel the feed line pulsing like the pump is doing something... we'll see!


will have more info later

looks like we're in for pulling the pumps. while ive got the upper intake off im going to find a cleaner looking used upper manifold to replace our pitted one, and of course reseal both pumps.


should be some pretty good carnage shots of the engine torn apart once this gets under way.

just ordered the rebuild bits and intake gaskets today along with the pump tool, so probably not starting until late next week when all the parts show up, and i can confirm our buddy in canada has a clean intake manifold for me to buy.


stay tuned!

brake pump rebuild parts should be here shortly...
stay tuned for some torn-down pics from this weekend

just popped the front brake pump off tonight and had a look around. looks like our front brake pump pushrod isnt moving. pulled a little bit and couldnt get it out, but waiting on RROC confirmation on the proper removal method - nothing in the shop manual on this topic. regardless it needs to come out for inspection/replacement.


pictures to come

just confirmed via RROC that the front pushrod is stuck roughly in the full up position (~1/2" sticking up above the bottom of the pump cavity)... possibly explaining why nothing was making weird noises, as its likely that the cam lobe entirely misses the pushrod at this point.
the spring pressure on the pumps is really low, and is the only thing that forces the pushrod back down (aside from gravity) so it could have fused itself in there from sitting parked too long - there was some evidence of moisture underneath the pump so i think this is the theory ill go with for now...


for kicks heres the cutaway view of the whole mess from the workshop manual. cutaway is drawn with the pushrod in the fully down position.



plan for this weekend is to tear the upper intake manifold off in prep for arrival of the new one, and see what i can do about unsticking/removing the front pushrod. hoping to pick up a new intake manifold next week/weekend, and possibly another pushrod if this one ends up being ruined in the removal process.
will also refurb the pumps after the intake manifold is off.

should make for some nice pictures

good news all around this weekend - push rod came out with some persuasion, nothing was damaged, and the intake manifold was a breeze to remove.


intake manifold off, just one bolt holding the whole thing down (once the fuel lines and couple hoses are unhooked). so far of all the things ive serviced on this car, this is probably the most well thought out system - easy to remove for service. was probably due for removal as the main gasket was in pretty sad shape.

shot of the corroded pushrod. we soaked the little chamber it sits in, in some penetrating fluid and eventually were able to hit it hard enough to knock it loose. bumped the starter and the cam was able to pop it back up, and out it came!

manifold/carbs... after a closer look i might try to get some new gaskets for a couple of the carb bits also... i have new stuff for the intake manifold

carbs broken loose

and this is why im replacing the upper intake

hoping to get my hands on some new parts this week and we should be in business by the weekend...
i still have to pull the rear pump while the intake is off, and service both pumps while theyre out, but those should be minor jobs this week.
