Family "T-wrench" performs P-wrench duties!

[dshepp806]

Just wanted share today's venture. First, a short background.

I always engage my son-in-law (M/Toyota Tech here in town) to provide his space (and hands, usually) for oil changes, balancing, etc....We recently changed out the Tranny fluid with M1 Delvac,...great improvement on the G50...plug showed no evidence whatsoever of any metals....just the very small sludge ball........

In ordered the wrong pads so we couldn't address this today but decided to go on with the flush....and the installation of all new flex lines (stock OEM rubber).

In any case, we always joke with him, calling him the "T-wrench",..who is also a "P-wrench, of sorts. He's put his time in just in our frequent conversations regarding the Porsches ,...so, he's tuned in. Has a great shop, too.

First time using the PowerBleeder but all went quite well. I'v had the car for over 3 years now and never checked/flushed this fluid before. Kyle (our T-wrench) was (is) a big fan of gravity approach, then finishing with the pedals. He wasn't too keen on what I was doing, at first,..but played along nicely,..off we go on a pressure flush. drove out various PSIs but stayed under the radar on <16 PSI...

Once we finished the work,..we normalled everything up and had a feel of what the pedal is now doing (not being touched once during our procedure/work), As soon as I hit the brake pedal, she was stiff, right where she always was,....relieved. On to using teh pedal pressure to finish....

We then work around the corners with the brake pedal application (pressure=feet= 2 1/2 pumps),...bled 'em all..and called it a day...took her out for a drive and she's right where she was before....EXCEPT for the CRAP I got out of those lines....I couldn't believe it...a pic is forthcoming. I attempted blowing through the line (both old and new) and sense a noticable difference...AND, THE GRAN FINNALI': It was the original frikin hose from 1/1989 !!!!!!!!!! (Reminds me of my alternator changeout last year,..and finding the original alternator/reg.....) No doubt, the hoses needed to exit the car....no visible swelling, but definitive cracks were noted in the +20 year old cable........(imagine that...)

She's gotten' much better (braking) with each outing this afternoon.......trying to get her settled so that she can lock the brakes if necc........new front pads due in next Tusday....the existing ones are fine, with only 50% gone,..the sensor is jumpered but we'll get it back to stock with the proper notched pads and a new sensor....I don't mind that idiot light at all.

It took us about 2 - 2 1/2 hours..., with Kyle doing the actual work...ran LOTSA fluid through, for sure.....went through 2 cans (almost).

Sure do like the pressure bleeding....I just need to get the speed valves installed now.

Some pics:











So: on goes the trek of the T-wrench (Master) turning P-tricks......kinda cool. I always get to work with him,..badgering him with torque specs as much as possible..

Good mornings' work, for sure......considering the shot of what came out,.....makes me want to drive another can through there....I'll tell you now,..THAT green container was completely cleaned prior to using it...no dooubt,..what you see is what I "GOT"....

Christmas Eve work,..yes,...well done, Kyle...and THANKS!!!!!!!!!!!

Happy Holidays to all.................

Im a HUGE fan of flushing brake fluid every few years, I do it on all of my cars. Now, since your car has a G50, flush the hydraulic clutch system too. Not very easy getting your hands on top of the trans and onto the bleeder screw, but it can be done.

It's on the schedule,..I seem to always forget the parts to make a full order,...a new slave cylinder flex line is on it's way. Having found the ORIGINAL brake flex lines in there, I'm sure the slave flex is the same.

Thanks,

Just for the information record:

Our approach was to pressure bleed, going around twice......tapping everything with a rubber mallet both passes,....................then twice around with the pedal pressure technique ( a few pumps,..hold it down...bleed it,..tighten it back up,...then release pedal). We saw no air on the brake pedal bleeds.

The pic of the container has mucho crap in it, for sure. The white dots are simply photo artifacts,..but that rusty orange-looking stuff (flakes?) was abundant. I had hoped to filter that sample through a cheesecloth or something and see what it "is"...I forgot to do this, just I forgot to sample the damned drainage for Lab testing (never submitted a brake fluid sample to Blackstone...).

I'm gonna put a few hundred miles on her, while waiting for the clutch flex line. Once it arrives, we'll be sure to swing back through everything for epilogue.

I was kinda' nervous about this process, never having done this before on the P-car. Took much time reading all the Pelicanites' posts and learned a lot (vicariously). This board is great! I was adament about using the Motive and leaving the damned pedal alone. A majority of people here seem to use both bleed methods.,.....so,..THAT'S what I did...and it worked perfectly.

I made sure Kyle knew I didn't have any spare bleeders (be gentle and use flair) and that the hard lines could easily be broken off if left to move. I had no worries about using the flair wrench, as he's done thousands of brake jobs (many cars) and uses this tool religiously.

Being that the fluid is hydroscopic,..and assuming the fluid's been in there a long time (3 years I know of), are there any concerns about the state of the hard lines' interior? Just curious............................

Thanks, again, to all who contributed to a successful job!!!!!!!!

My best,

Doyle

ALSO: yesterday, right after the work...she would (eversoslightly) pull to the right when quick pressure was applied to brake...again, VERY slight. All of today's runs produced NO pulling at all...! I can hit the brakes (no hands on the steering wheel ) and she brakes straight-ahead....guess that piston settled in?

Best,

Jeez, Way busy Christmas. Good for you.

Nice to have access to the shop and the Son-in-law. Seems like he sure treated you right.

Brake fluid on mine was done a year ago and the clutch was done about a month ago, so I should be good for a little while.

My lines are original as well, and the mechanic has given it a clean bill of health, but I should probably replace mine as well.


How busy is the Son-in-law? :>)

It's up and down for him (personally). Some days are insane (2 motor rebuilds),..others are slow...you know how the market is these days.

For example: yesterday, we started on the brakes around 9 A.M. and finished up around 11:00 -11:30 A.M. (ran a lot of fluid thu!!!) This was the first time for me (and him, too, on a 911). Upon removing the first wheel, he remarked "Ah, just like a volvo"....he didn't want to go the pressure route, at first, but we did it with the brand new Motif pressure bleeder that I bought about a year ago!

He treats me right and I return the favor. For example: I've got to see my P-wrench for a problematic number #1 spark plug extraction within a few weeks. I had asked him what he would charge for the brake work (just the flush) and was quoted $150.00. In the meantime (waiting to get in) we decided to go ahead and do it ourselves. I don't know what the P-wrench would of charged with the added labor of replacing 4 brake flex lines but I would assume another $100 bucks (to be gracious)...Being Christmas and stuff,..I had no problems handing that guy $250 for his time...hell, we even threw the wheels on the balancer to check them...........I couldn't ask for anything more as far as resources.......we just have to keep the service manager happy !!!!!!!!! He would have easily have done it for nothing.......

Back to your question,..I took the car out and came back,..reporting the findings,..prepping for the next service phase (clutch-slave-flush),..then went and got lunch...consumed it,...hung around a bit...went to the bank: get cash,..return.........he left out at 3'sh with no Toyotas (or any other makes, for that matter) showing at his doorstep for the day......as you know: these fellows work on commission (labor rate payouts), although the Master Tech gets a piece of his teams' revenue,.................................glad to help him out on (what we call) "the P-side job",.......we both learn,..I get to pester him with torque values...it's all good!!!!

Thanks!

I'd go ahead and get those flex lines out there........again, I noticed appreciable differences in the new vs. old lines by simply blowing through them...even without instrumentation to quantify, one could tell the difference.....

slave(clutch) is next......

Wow Doyle, way to go!

I just got the fluid, ss lines and the pressure bleeder from Mrs Claus/Steely.
Shot of the crap in the basin tells me I am overdue too - looks like I can count on some improved performance. My lines are original as well.

And you're very fortunate to have grade-A help - I'm envious - sounds like you know how to return the favor. Thanks for the post and great job!

[dshepp806]

Whatever you do,...don't let that reservoir go dry....I'd also set the motif into a trash bag while it sits in your bonnet. I used the Motif DRY (no fluid in there).

They say the clutch feed line is a bit higher in the reservoir than the brake feeds so keep this in mind when bleeding the slave, as you may suck air at the 1/2 level in the reservoir (may want to fill more often when doing the clutch slave.

Release pressure at the Motif neck (not the reservoir neck(. [DUH] )
