Biggest BRAKE JOB of my Life!! (RARE Abandoned Audi Turbo - Part 6)

[@TheRealJerseyJoe]

Speaking as someone who has done a lot of work on Audi's in the past, the chances of something else breaking or going terribly wrong during or after the initial test drive is nearly 90%.... LOL ! You've got a lot of patience Ivan... Respect !

[@needadate]

The sad thing is that they broke as much when they were new... Very good parts crapily put together by undertrained Gastarbeiters who didn't give a single F since they would be kicked out of the country in three months anyway. As a diag specialist in a VAG shop way back when, I have numerous stories of screws drilled into harnesses, terminals barely making contact since they were pressed on still-isolated wires and the like... Worst part is that it could take years before the problems would show up - enough to have the car out of warranty.

[@lo1234-w9r]

I'd be worried about that overheating problem after only 1.5 miles. That sounds like a blown head gasket.

[@mikeafa1]

I think there is air in the system. Ivan can't even check the heat because the heater core is bypassed. Are all coolant and looped heater hose hot too?

[@adamtrombino106]

I had to watch this 'brake' special just because I recall seeing 1 of these come in for tires when I worked at GoodYear in the mid 90s thru '03.. There were like 4 techs standing around the frt end of that car all saying, "How the heck do those brakes come off!?" Crazy idea, but leave it to the Germans to think WAY outside the box! Great series Ivan!

[@VWERIC10]

You unbolt the entire caliper, from the Knuckle? strut assembly, rotate it away from the mounting ears, and remove with the rotor. Installation is, reverse procedure, load the pads into the caliper assembly, slide it onto the rotor, and bolt everything back on together.

[@MarzNet256]

The front and rear brakes on that car are sheer insanity. Those german engineers really went off the deep end. It's like they had a contest for who could come up with the most convoluted design.

[@patrickmaloy5262]

Your breathing life and reliability back into the Audi. In restoring a rust free 1980 300 SD turbodiesel I experienced almost the same issues what you're experiencing with the repairing of the Audi. It took me two years to accomplish. Once fully restored, I moved on to other projects and sold the 300 SD to a neighbor. He wanted a safe car for transporting his kids, and two car seats were installed. The 300 SD had several owners after me and remains in excellent shape. It's been repainted the original color, and looks sharp. It's not a lady's car, and I've never seen a female behind the wheel., I know this because it's never moved from my neighborhood, and I often see it cruising the streets always driven by a male. After I finished restoring it, the old Mercedes was super reliable.

[@catranger01]

19:30 It looks like the front brake disc pad manufacturer forgot to peen over the stud that holds the spring clip. You could have tack welded the head of the stud to fix it.

[@stevefleck5892]

My thoughts exactly. I think some frustration crept in...

[@sstocker31]

Yes, I as well had the same thought. I'm just glad it's not me working on this POS.

[@2aminitials]

That clip needs put back on before it possibly causes that expensive rotor to get eaten up.

[@Garth2011]

Yessiree...looked that way, just carefully peen that stud a bit. Any blacksmith/wheelright would've !

[@retrorenovo]

Came here for the 'eurotrash' comments and boy I was not disappointed. I think the eurotrash label is somewhat accurate, but misplaced. We can't let the Euro governments off the hook for forcing mandates to a variety of features or abilities (safety,mpg,emissions) while blaming the manufacturers for implementing the mandates. We're well on our way to this here in the states, and the summary "Never in my life would I own" or "Never would let this into MY shop" comments will come home to roost soon when that's all we have left. Overly complicated digital solutions to problems that did not exist to serve mandates that are rooted in falsehoods. Not by choice, but because it's being foisted onto us by regimes that do not want private transportation in the near to mid term future. If you're here reading this in 2023 and still think THEY want YOU to be able to have your own private transportation - and - all of these complexities and flawed engineering decisions are simply an 'accident' or a result of mismanagement or exclusively euro eccentricities, I have a bridge to sell you. I’d go as far as saying this owner is obligated to keep this thing road worthy out of spite alone. Ivan is doing us all a favor here. Cash for clunkers, ethanol in the gas, kill switches, front rear and side cameras, EVs - all an accident I suppose.

[@vpimike2646]

Other than the German technology, this brings back Similar memories, each time I fixed one thing I'd find something else that needed to be repaired. Eventually, I won and did get it up and running and drove it for several years.... Good luck Ivan, you'll get there!

[@lvsqcsl]

I had a customer one time that had a 1980 Oldsmobile Toronado with rear disc brakes that had calipers that operated the way you said and I had a 1987 Lincoln Mark VII that was quite similar. The ol' Marquis actually has a separate set of miniature brake shoes inside the "hub" on the rear rotors that act as the parking brake. Out of all the places to source brake rotors, I would have thought the Czech Republic would be the last. I know years ago when you, Eric O., and Paul Danner was on your way to Eric-the-car-Guy's meetup that it was a general concensus that none of you like working on European cars. Paul hated the fact that information was difficult to get and you and Eric agreed. I bet you appreciate all of your cars now, Ivan, even Mr. Rogue. GREAT VIDEO!

[@PineHollowAutoDiagnostics]

Ha I don't care much for modern Euros, but 90s and older are fun to mess with and stretch your brain 😅

[@Sandmansa]

I believe Audi had engineered into every car they made, built in job security. lol. Anyway, it's come a long way since it was dropped off. At least now, it can stop and go. The door locks and windows are working. And the dash is back in. It's turned into quite the restoration project. I believe most of us have run into this situation where you start 2nd guessing if taking on a job of this magnitude to completion is actually worth it. As long as the engine, trans and body are sound, the answer is always, yes. The reward at the end is priceless. You're doing a fantastic job so far. Keep at it Ivan. I can't wait to see what's next.

[@jabberwockytdi8901]

The adjuster in the rear calliper effectively has one way clutch to allow the screw to take up the slack but not go back in when you apply the handbrake. The exact design vary over the years but those things ae in millions and millions of cars , and they work fine untill they don't - aging seals letting moisture in to the lever mechanism, lack of brake fluid changes causing issues with the internal adjuster mechanism etc.

[@eddiereichel9354]

I wonder how many text messages this repair had back and forth.

[@major__kong]

That parking brake cylinder reminds me of a DeWalt cordless drill I took apart to replace some parts. Even with pictures I took during disassembly I was struggling. I think I needed 4 hands to get everything slid back into the housing properly, and I still couldn't get something to work right. I put a dollar value on my time, and I ultimately decided it wasn't worth my time anymore and bought a new drill. It was 20 years old anyway. Gave it to a smart and mechanically inclined high school kid and told him it was his if he figured it out. I suppose those rear brakes aren't available anymore, so failure isn't an option.

I hate working on these rear calipers. Looking at the video, these are done, they have to move more freely, they don't seem to retract even with the springs. Handbrake will stay slightly engaged when used. Another common problem on VW and Audi.

[@closertothetruth9209]

[@BY504A]

I made a lot of money over the years replacing rear calipers with frozen up emergency brake adjusters. Most people never wanted to pay for brake fluid changes and the result was that they ended up paying a lot more for new calipers.

That coolant pipe hole might be a weeper? For draining? I worked on a 2001 A4 and it had an air bleed procedure that required the upper heater hose to be backed off until a hole in the pipe was revealed. There were actually lines marked on the pipe indicating the "bleed" position and the "installed" position

[@PineHollowAutoDiagnostics]

Ha that rings a bell... Think it was a 96 Audi A4 V6 that I came across that weep hole feature. This Audi decided to make its own weep hole at the bottom of the heater hose pipe 😂

[@ricebike]

Oh would the burping funnel tool can help in this case? It puts it as the highest point for air to escape from the systems that I've used over a decade. I'm scared to undo the air bleed valve on some vehicles and just do multiple heat cycles on the driveway to make sure the fluid level is constant I purchased the original Lisle tool kit 2 decades ago 😅

I don't know if anyone else noticed but that spring clip on that brake pad that fell off was because it was not staked on in manufacturing. The old pad shows a rivet head shape holding the clip to the pad. The new one is just the post which was never peened in place. You might be able to peen it with a sharp punch. Just make a bunch of punch marks and the pin will expand holding the clip in place.

[@SomeRandomHuman717]

@@PineHollowAutoDiagnostics If replacement calipers are available for a decent price, then replace. If not, then you might need to disassemble the parking brake actuation mechanism on the caliper, check for corrosion or scoring, and if needed dress up the pivot pin and bushings, relube, and reassemble.

[@janolsson2037]

Undo spring retainers and remove spring. Then likely a nut that holds the lever to remove. Then seal on the top of shaft will be press fitted in needs to come out then shaft out, clean up and grease. The special tool for the caliper internals is a reverse thread nut with a step and flange and the thread matches that spiral on the shaft. 90s Toyotas were very similar

[@ert870]

If you clean it up nicely, lube the levers shaft (plus add lube before and after the last conical seal before the arm that the cable connects to) and assemble with new seals it won't rust. Lube is the keyword. I rebuilt my Audi rear brakes 5+ years ago a no problems ever since. Without lubing the shaft it rusted in 1-2 years so that brakes started to drag again. Lube keeps the moisture away.

[@cmeier7560]

this mechanism works really well and was still used at least up to the 2010s in most of the lower end Volkswagen cars, like the VW Polo or Seat / Skoda equivalents. I still own one car line this and have already rebuilt the driver side rear brake on two of them, so apparently the driver side caliper is more prone to failure (IMO this could be connected to curbside parking with more fluid ingress on the driver side). Only the 'better' or newer ones with electric parking brakes are designed differently (and you need software to "rewind" the caliper when doing a brake job on the rear wheels).

Awesome job Ivan! also keep in mind those old school ABS systems have hydraulic brake accumulator instead of a vacuum drum.. I had one go bad in a different vehicle and didn't hold the pressure. Eventually burned up the electric pump, as it was running every minute the car has been sitting with an ignition on. Once the electric pump finally seized, I lost the power brakes. Might be something to look into if the brake pedal feels funny or an occasional brake light comes on under load.

Actually there is a shut-off valve going to the heater core controlled by the fancy HVAC system, so there is another dedicated bypass for the engine... But yes, on some cars the heater core is a critical part of the cooling circuit :)

[@dwalmop2]

That persistent brake light is probably from the "brake bomb," which is almost guaranteed to be shot and depressurized after sitting so long. The technical name for it is "brake accumulator." I don't think that's your spongy brake issue though, you've probably still got some trapped air. You can sometimes find good accumulators, but it's not easy. Luckily the 200's had the more common ones, as opposed to the early 80/90/coupes, which had a slightly different style. Those 3B engines are an absolute gem and are extremely durable, but they can be difficult to bleed the cooling systems on. Highly recommend a vacuum system to refill the coolant. Are you sure the boiling sound wasn't just the afterrun coolant pump (under the intake manifold)?

Had one of those cars put 80k on it and nothing but trouble thanks to a rod bearing spinning on it the thing is now in car heaven

Intricate yes, but nothing like french cars who use plant oils for rear ends, and special hydraulic oils, and often people who don't know top up with ATF and the whole hydraulic system blow up, and every seal will leak, and oil pouring our from underneath the car. Very very expensive to fix 🤔😱

Ivan you should get a quickjack or even better, "My lift Stands". Stands the cars up very high and pretty affordable compared to a lift.
