Toyota Sienna Brake Master Cylinder Replacement (2004 - 2010)

[@petenelson8136]

I don't even own this car, but I love watching how you do this kind of work and how you explain everything. My Dad had a 1972 Toyota Corolla that I learned on. Did 5 valve jobs (yep it burned valves like crazy), rebuilt the carburetor, master cylinder, and did a ring job on it. I did all this between 15-18 years of age (now 63) and that experience served me well over the years working on my own cars. I've always believed in sweat equity and doing things myself whenever possible. Thanks again for putting these videos up, you do an outstanding job.

[@hardlymovingpro]

Thanks for sharing your background story. I started at 6 yrs old replacing the inner tube on my bicycle. Then moved on to mini bikes, mini cycles, motor cycles and finally in to cars.

[@AM-nn9sv]

Still, one of my favorite mechanic channels. Thank you for the content.

[@hardlymovingpro]

Glad you enjoy it!

[@SnakeBloodlines]

Oh Yeah! Thank you for this video, made this attempt on our Sienna and didn't realize the shroud needed to be completely removed then gave up on the job. Will certainly get back in there now! Thank you.

[@hardlymovingpro]

Better to have tried and failed then never having tried at all!

[@robertdiehl9003]

Excellent video and repair. This man is fearless when it comes to auto repairs. He tackles any job !!!!

[@hardlymovingpro]

Thanks!

[@salvadorsepulveda6415]

Always have a lot of respect for mechanics that work on all makes of vehicles. You do great work and your knowledge is vast, thank you. Blessings

[@hardlymovingpro]

Thanks!

[@dellkickass]

You're master making straightforward details videos. Thanks many videos from you

[@hardlymovingpro]

Thanks!

[@oldvetwhotravels.5326]

Glad to see the "Master" is still at it. Hope you & your family are doing Great!

[@hardlymovingpro]

Thanks, you too!

[@oldvetwhotravels.5326]

You are very welcome Sir.

[@Afrattzz1]

Glad to see you back. Great video as always!

[@hardlymovingpro]

You bet!

[@Afrattzz1]

Hey hardly moving. I have a 2007 Mitsubishi Galant and the rear brakes are severely dragging. I replaced the brake pads and was able to compress the pistons. The pins are not seized. I thought maybe the hoses were bad but I replaced those and still having the same problems. Could it be the master cylinder?

[@evanepp]

Another excellent video! Thanks!

[@hardlymovingpro]

Glad you enjoyed it!

[@Tom-jx9te]

Great, watching a “master” at work😊 I was thinking about doing this job on mine but it’s such a pain getting to the master that I’m gonna let my mechanic do it. It’s like 60% of the job is getting that stupid shroud off.

[@hardlymovingpro]

I hear ya!

[@sivucit]

Hi. Great work. You used a tool to connect crowfoot and extension. What is that please

[@hardlymovingpro]

I have the tool listed in the video description.

[@issacr.1145]

I was just wondering, shouldn't you have bled the air out of cylinder on a vise before connecting to proportional valve on the booster? Did you have any problems with trapped air in your lines? Just wondering, cause several mechanics have told me you have to do this to make absolutely sure there is no air in your lines.

[@hardlymovingpro]

Good question. Since the reservoir isn't attached to the master cylinder, you can pump the brakes with the cylinder attached to the booster with a temporary plastic service line running from the cylinder output port to the reservoir. Pump the brakes while someone is watching the air bubbles, if any, are being pushed out from the cylinder.

[@Odeleyepeter-ob1lb]

Very perfect and understandable thanks

[@hardlymovingpro]

You bet!

[@MooncrawlingRocks]

I'm gonna go for it on my 2006 Sienna and using your video. It didn't show, but did you need to empty the braking fluid first?

[@hardlymovingpro]

That would be a good first step to stop a mess.

[@delroyjohnson36]

Very Good 👍🏽 Job

[@hardlymovingpro]

Thanks!

[@anastasiapitt7328]

Was wondering if you know the name of the item that connects to the master cylinder. The piece that is underneath it.

[@hardlymovingpro]

I think you're referring to the ABS control module.

[@onkarsingh6224]

The guy at o Reilly told me I might have to bleed from the master cylinder itself before replacing. Is this true? Can I just start removing the MC without bleeding until the new replacement is on?

[@hardlymovingpro]

Bleed BEFORE replacing? Nope.

[@Galvathorax]

When I place the new master cylinder onto that sub assembly housing. It's not flush. Starts off with about a 1/3" gap I can't push it flush manually. Should I bolt it down until it's flush or is there something wrong with the piston in the sub assembly that's not letting me mate properly?

[@hardlymovingpro]

It should be flush. May have to wiggle and giggle it around.

[@parkgrovedriving]

When you put the new master on , was it hard to push the new one on to the booster?

[@hardlymovingpro]

There's a little back pressure since the master is spring loaded.

[@mkl5448]

So it's not necessary to bench bleed the MC then? Because the reservoir does not sit on top?

[@hardlymovingpro]

You can but you'll need to detach the brake fluid reservoir from the chassis to attach to the new master cylinder. This will ensure no residual air pockets in the new cylinder.

[@mkl5448]

@@hardlymovingpro makes sense, thank you. Great video by the way, very informative and easy to follow.

[@Chris-yj4cw]

Hi, my break light and abs lights come on and sometimes when i break its like i slam on the breaks. It seems to mostly happen when it's cooler. Any ideas what could cause that?

[@hardlymovingpro]

Difficult to say without being onsite.

[@landshass2849]

Why are you disconnected on 1:21 is either and windshield radio antenna or wiper blades defroster. If there's an antenna on the fender, this will be the defroster and not all siennas comes with it.

[@hardlymovingpro]

Believe it's a rain sensor. The rear glass should have the antenna built into the glass.

[@OldmanJM]

Thanks for the info, I think I will just pay someone to do it.

[@hardlymovingpro]

Auto repair not for everyone.

[@OldmanJM]

@@hardlymovingpro I do lots of my own repairs, even post videos about it, but I like to watch videos like this to see how involved the repair will be first. I am certainly capable but it looks like this one is a little more involved than I would like.

[@hardlymovingpro]

The master cylinder replacement concept is the same for most cars and trucks. The only thing different with this car is the fluid reservoir isn't attached; that next time I would attach the fluid reservoir and hoses to the new master cylinder and pump out the air pockets before attaching to the brake booster.

[@luisamoa2500]

No need to bench bleed this version?

[@hardlymovingpro]

I guess you could if you attach those reservoir hoses but I flushed out all the old dirty fluid afterwards.

[@roadtaco3924]

Tks 👍🏾

[@hardlymovingpro]

No problem 👍

[@EdwininfanteLeocadio]

Wow great work, Just became a subscriber. I wish I could bring my sienna to you. I would drive it anywhere in the country just to get the right work done. Let me know if it's possible.

[@hardlymovingpro]

Thanks! I live east of Memphis TN. Had some subscribers come over to get work done.

[@EdwininfanteLeocadio]

@@hardlymovingpro I live in NYC, I just got a 2005 sienna a week ago. I've only driving it twice so far. But I know it's probably going to need some of the work I've seen in your other videos done to it. It has 185 k miles. I have no records of any service. So I don't know what does it needs

[@hardlymovingpro]

I travel to NJ to visit my mom every 6 months. Might be able to help you out. Send me an email.

[@EdwininfanteLeocadio]

@@hardlymovingpro OK cool 👍🏽, but what's your email, I can't find one on your channel.

[@puerco567]

but what about when you press the brake pedal and is hard to push? Even if the car is running and brakes lock

[@hardlymovingpro]

Not if the brake booster is working.

[@puerco567]

@@hardlymovingpro Thanks but parking brake was the problem and today I got my sienna back

[@hardlymovingpro]

[@mariovaldez6811]

That not good You don't need to remove everything. For replace that

Ok...thanks for sharing!
