Master Cylinder and Brake Booster Replacement with Basic Hand Tools

Master cylinder and brake booster replacement. *Quick note, at 1:35 I state you need a crescent wrench. It's in fact a flare wrench*
The brake booster provides assistance to the braking system. In simplistic terms, by having a brake booster installed on your vehicle, it does not require you to place a great deal of force on the brake pedal to stop the vehicle. The master cylinder holds the brake fluid. Additionally, it uses hydraulic pressure to stop the vehicle.

Love this vid. No long, drawn out intro… just straight to the point and how to do it. Well done!

[@BewareTheLilyOfTheValley]

My repair guy was doing some other repairs for me and mentioned that my car needs a brake booster replacement. This...seems quite far from what I had given him to install on my car (spark plugs, ignition coils and gasket valve seals to stop oil from leaking into my spark plug wells), but okay then. Issue is, he tells me GM stopped making the parts for mine in 2012 so he's having trouble finding a replacement. He did say it was a cheap part though (well, cheap in comparison to many car parts) and easy to install. He mentioned needing only a wrench...and after watching this, I see he was rather right. Might have found a website to help him out so if I don't hear back from him today, I'll check with him again tomorrow to ensure it's the correct part and order it myself or referr him to the website. But I wanted to learn more about this brake booster and your video did that so thank you.

[@steveoden]

Great video!

[@jaywholoveseveryone1721]

Thank You!!!

[@bolobrown814]

Awesome Bud bro

[@elimaki4833]

That was awesome little stick trick with the seat so you could do it yourself

[@paididoy]

The problem with this is that you keep on traveling from your car seat to pump the brake 5x and hold the pedal down then go underneath the car to loosen the bleeder valve. You have to it at least 3x each brake lines, so 4 brake lines x 3 (number of bleeds) = 12 X

[@luciohuet8513]

Great video.

[@nickandro127]

thanks

[@fwaters6644]

So with this vehicle you don’t have to worry about the length of the booster’s output rod?

[@waruiotoko378]

You deserved a subbed..done

[@mechanoid5739]

Is there a special way of bleeding brakes if the car has an ABS unit?

[@anandasene]

I want to fix a new booster to the daihatsu f50 can you please advice me?

[@koreymayo8884]

Is the gasket between the booster and master cylinder reusable?

[@schulmj69]

Thats called a Line wrench not a Crescent Wrench

[@MichaelScott-hi4qg]

schulmj69It is actually Called a flare nut wrench mainly used for lines though.

[@greglawson8001]

Brake line wrench lmaoo

[@YalikemyTigerBeat]

It’s a crescent Allen

[@blueshirthandyman8460]

It's a hammer lmfao.

[@TheOnlyOwnedbyCow]

Do I need gaskets for the booster to the firewall and between the booster to the master cylinder?

[@youknowkbbaby]

Can the vehicle be brought to a mechanic to bleed the breaks after you finish? Or will you need to bleed the breaks immediately before driving it?

[@austindurham6472]

do you have to remove the brake fluid if you're just replacing the brake booster?

[@CHAGrady]

No you don’t. Just be careful you don’t damage the brake lines as you need to move the cylinder away from the booster.

[@nimster64]

About how much does it cost to have one installed

[@donsal.t.1765]

So if my brake booster is leaking air by the brake pedal it's most likely my booster and not a hose?

[@randallthelizard5209]

I have a 1987 El Camino and I'm not sure if the brake master or the brake booster is out how can I tell?

[@jojones7772]

When the booster goes bad the brake hiss like crazy and the engine idle will go up a bit! The master cylinder going bad causes the pedal to go all the to the floor as far as I've learned. And it is best to replace both if your booster stops working. A bad master cylinder will ruin a new booster!

[@CHAGrady]

To test the brake vacuum booster, when engine is off pump the brake pedal several times hard until you feel the pedal hard, hold down the pedal after the last depress, start the engine whilst holding in the pedal, the vacuum should work and you should feel the pedal sink further as it’s being assisted by the vacuum booster. If it doesn’t, it’s your booster at fault.

[@randallmoffitt4434]

How many people need to mention that it's not a crescent wrench? Holy shit!

[@hendricks177]

I got a 91 Ford f350 and im having trouble with my truck. My brake pedal goes all the way to the floor.

[@zachblackburn235]

do you bleed brakes before installing new booster or after?

[@randallmoffitt4434]

Afterwards.

[@randallmoffitt4434]

It's the last thing you would do

[@josebarragan5234]

What year, make & model is that vehicle you are working on?

[@CarsNToys]

This example was from a '73 240z but you find the layout on many, many vehicles.

[@josebarragan5234]

CarsNToys Thank you! I just need that exact master cylinder for a 85’ toyota pickup!

[@Palo_Azul]

After doing all this how much do you bleed the brakes? I bled the shit out if my brakes and my brakes arent engaging.

[@CarsNToys]

What technique? Bench bleeding or bleeding at each wheel? I typically do this: kzbin.info/www/bejne/naTaaYasqNplnZI

[@tommyrich3038]

Good Video, looks like a crows feet wrench

[@CarsNToys]

Thank you. Appreciate the feedback!

[@MrNatesluvs]

@@CarsNToys yes it is also known as flare wrench

[@williamsliemers1758]

Not a crescent wrench... tubing ; flare; and that's it.

[@CarsNToys]

Thank you.

[@usmcken5580]

It's not called a Cresent Wrench. It's a line wrench. Other than that Good Video.

[@jerrwoodyify]

Line wrench

[@CarsNToys]

Or flare wrench. Thank you.

[@bigonexeon]

thankyou dont you have to bleed the mastercylinder

[@lampsocket]

Line wrench not cresent

[@racyfreeman317]

Notice no background music, screaming kids, pet running through etc......Way to make a helpful & informative video, so all you, film in the dark......cell phone one hand video.....skip around video, people should take note on how its done!!! Great video...

[@CarsNToys]

Thank you! I appreciate the feedback and support. Cheers

[@brittprincepublications]

That is not a crescent wrench. That is a brake wrench. The other one is an open end wrench.

[@CarsNToys]

Thank you. Yes an honest mistake - flare wrench

[@jeffreycunningham7915]

It's not a "cresent wrench". Cresent is a brand of tools, not a type of wrench. It's a flared box wrench or something to that effect but it's annoying as shit when people call an adjustable head wrench a cresent wrench but to confuse a flared wrench with a "cresent wrench" which usaully is a reference for an adjustable head wrench makes me question the credibility of the mechanic

[@CarsNToys]

Yes, it's a flare wrench. Thank you.

[@misterbulger]

Definitely dont use an actual crescent wrench unless you want to strip it. I just bought one of your wrenches today. It says flare nut wrench on the package.

[@CarsNToys]

Yes, flare wrench is the correct one.

[@johnnyjohnson5571]

I thought a “crescent” was really called a “Mexican” wrench ?

[@CarsNToys]

Good catch! Yes, it's a flare wrench.

[@davestarr7112]

How to quickly cause a viewer to lose confidence. That is a flare nut wrench, sometimes called a tubing wrench. Cresent" is a brand name most commonly used for an open-end adjustable wench with a thumb wheel that changes the size. The very LAST thing you want to use on a very tight flare nut. Stay away from MY brakes.

[@purewhite84]

That's not a crescent wrench lol. Got a mechanic KZbin channel and don't even know what a crescent wrench is....

[@erinkusch7322]

DOWN BOY!!!! DOWN!!
