JUNKYARD RESCUE! Buick Scrap National Part 6 - Brake Upgrade

I swap the failing Power Master for a Vacuum booster brake system so the Scrap National will STOP! This is the final video before I drive this car for the very first time after all the work I did to make it road worthy once again!

You've earned a spot in heaven for the rescue. Cant say the same for whoever junked it.

[@ClassicGBodyGarage]

Yeah it's great to save such an iconic car

[@Ronaldl2350]

I just found your channel. I started my mechanic career at a Buick dealer in the eighties. Worked on a lot of Grand Nationals. Wanted to buy a brand new one from the dealer I worked at, but never got the opportunity. I miss those cars . Thanks for sharing and getting this car back up And running.

[@ClassicGBodyGarage]

Very cool! I would have loved the opportunity to do that. I am 45 so these cars were everywhere when I was younger and happy that I was able to be part of the times when they were on the roads as daily drivers.

[@wtdonovan]

Satisfying swap to the vacuum assist! That run down of systems and availability, the direct comparison of parts differences are invaluable to anyone out there with these kinds of questions. Excellent content man.

[@ClassicGBodyGarage]

Yeah hope it helps others out. Thanks for watching!

[@wyattoneable]

It's good to see you back. I'm glad you saved this car.

[@ClassicGBodyGarage]

Good to be back!

[@28adam28]

Nice Brian! Having done this on mine I can say the pedal was the most annoying and painful (MY BACK!!!) part of the process. Electric ratchet was a lifesaver. As for people asking about enough vacuum, I even have a bigger cam in my GN and it's fine. Powermaster is such a death trap, you can tell people how hard the brakes are when it goes, but most don't believe you. I experienced it once, and that was enough for me. The vacuum brakes went on, they work great.

[@ClassicGBodyGarage]

Yeah all true here. Was a bit of a job but not bad at all with OEM parts. Brake pedal was a brick on this car and didnt stop at all. Will be fine with this set up.

[@boss12]

Glad to see the progress. I hope this thing is ready to go now. This would be such an awesome driver quality car.

I remember working on the power master units when they were still under warranty. They were a problem back then. Lol. The grey switches in them had a recall as well.

[@jordanwiley4582]

you can also use the booster from a late 80s/early 90s b body caprice.

[@ClassicGBodyGarage]

Yeah true, didn't think of that. Thanks for bringing that up!

[@AutoAuctionRebuilds]

My Monte Carlo has serious brake issues. I’m starting over from scratch. All new lines, hoses, master, proportioning valve, drums, etc. doesn’t look fun at all.

My grandma had a 1979 or 80 Buick regal green on green hard top. She wanted to give it to me but for a first vehicle but I couldn't fix it motor was locked up. Didn't have money.

[@ClassicGBodyGarage]

Ah bummer !

[@BrooklynBounce]

I’m doing this job tomorrow on my GN. Not looking forward to working under the dashboard

[@ClassicGBodyGarage]

Little bit of a pain but you will get through it. Take your time so you can do the job the right way.

[@forterierocks]

I still can't believe someone would scrap a GN they easily could have sold it for a lot more then pick and pull gave them.

[@ClassicGBodyGarage]

yep true but many don't have the resources to sell a car and in some cases its easier to send it off to the yard.

[@jonsworld5307]

my guess is someone died off and left it and the wife didn't know any thing about it just thought it was a junk car

[@1984buickboy]

83, 84, and early 85 used the hydroboost.

[@ClassicGBodyGarage]

Yep talked all about that

[@DONTCALLMETHAT]

I love this car. I recued an 85. A complete car. Floors were rusted but the rest is great but question.....Can you tell me where I can get g body bucket seat rails?

Thanks my man! Its about there! Make sure to check out the final video coming in a few weeks.

[@barryismygod]

How does the vacuum boost brakes work with a motor that doesn’t make a lot of vacuum due to boost?

[@jkaps1173]

Motor makes enough vacuum and important to check lines for leaks.

[@ClassicGBodyGarage]

Find out in the next video 👍

[@johnnyruckiz]

Good evening… Great Video! If the Power Master is still available how much are you asking for unit?

[@ClassicGBodyGarage]

The car is owned by Pull A Part so it will probably stay with the car.

[@olddirtyburt7522]

Seems like a very high idle, even in gear. 1750 is tough to hold back even with good brakes.

[@ClassicGBodyGarage]

True, i also think that tack is a bit off.

[@DONTCALLMETHAT]

First to show to here

[@ClassicGBodyGarage]

Thanks for the support!

[@rattlerrestore3106]

IMO if hydroboost was an option that’s how I’d go , nothing stops like a hydroboost setup

[@ClassicGBodyGarage]

I am sure it works great when it does but the vacuum boost is what will remain as long as I own this car.

[@jasonwright3640]

Good video. Are you going to sale the brake pedal

[@ClassicGBodyGarage]

It will stay with the car most likely. Stashed away

[@GrandNash-bk2kq]

I recently did this swap to my 1986 grand national and my brakes barely work. I tried bleeding the brakes multiple times. When I put the car in gear with my foot on the brakes I have to push the pedal down extremely hard for it to stop. Do you know what the issue could be? The brake booster and master cylinder brand new

[@ClassicGBodyGarage]

You need to change the pedal as well cuz the leverage point is different. It worked perfectly fine on mine and others who did the swap I know using the same process.

[@runescape51501]

What year Monte Carlo ?

[@charlieb308]

I’m adding a 383 stroker engine to my 86 Monte Carlo SS, replacing the Quadrajet carb, do most carbs have that vacuum line in back for brakes? Or will I have to fabricate something?

[@ClassicGBodyGarage]

I dont know too much about aftermarket carbs but if the large port is not in the base of the carb then just run the booster directly to a large vacuum port coming off the intake.

[@charlieb308]

@@ClassicGBodyGarage thank you

[@sbf_fox2434]

So why did GM put the complicated Power Master or Hydraboost systems on the turbo cars compared to the tried-and-true vacuum power brakes?

[@ClassicGBodyGarage]

My only guess is that it may have been a safety requirement because vacuum is not sufficient enough for a vacuum booster to work at its fullest capability upon full throttle or when boost is up if a panic stop occurs.

[@JexuanyGuerrero]

I have an 82 Cutlass Supreme with hydro boost. I put a sbc 350 with the one belt pulley set. It’s really hard to steer on stand still. Wanting to switch to vacuum, would I just need the booster and master cylinder or would I also need a pedal?

[@ClassicGBodyGarage]

You will also need the pedal from the booster system.

Do you have any video showing how to remove and install a timing cover with the engine in the vehicle and without lifting it with a hoist... Need to replace my timing cover and its seal and gasket, but I have no way of lifting or removing the engine... Any advice is greatly appreciated...

[@ClassicGBodyGarage]

Need to know what engine and I can give you some pointers but no I don't have a video specific to any timing cover removals. I have don't this myself on a small block chevy and didn't have lifting the engine.

[@tynandill926]

@@ClassicGBodyGarage had an older mechanic tell me this... "I have never pulled a pan to do timing chain on a sbc. I was taught by a chevy dealership tech on how to do it back when I was 16, I am 51 now, we always trimmed the corners off the back side of the rubber gasket support, used 2 small phillips screw drivers to "pry" down on cover untill it slipped into place, ya it takes a little work but thats how we always did it."

[@ClassicGBodyGarage]

@@tynandill926 Ok so he is right. Removing the cover is the easiest part but installing it very difficult because the U-Shaped rubber seal that goes on the bottom needs to be compressed for the cover to fit back on and the ends of the rubber seal need to be trimmed or it stops the cover from sliding into place. My trick is to trim the sides a little, remove the front half of the oil pan bolts which will allow the pan to flex a bit so you can fit the timing cove back on. You MUST use RTV then to reseal the pan gasket area as well as the corners where the rubber timing cover seal meets the oil pan which is the proper way to do it anyway. Hope this helps.

Cheaper and easier to install

@@chickenfoundation9323 I hear ya. Still would go hydro if I ever bought another Turbo Regal. Power master is like a bad day waiting to happen...

Vacuum boost is also way more readily available. Its not easy finding a hydroboost system with all components and functional.
