As mentioned in the video, this week I am restoring a part from the E30 that I have already restored. So I purchased this brake booster and master cylinder to show the process. This particular master cylinder would need serious internal work or replacing altogether. I purchased an internal seal kit but when I got in there, the second half of the assembly was well and truly stuck. So, I just got on with the aesthetic of it as I'm not actually using this on my E30. I will show the process of replacing the seals in my actual brake master cylinder in a future video.
Firstly I disassembled the booster and master cylinder. I then degreased everything before plugging any holes with Polydoh. Once sealed, I blasted them both to remove any paint and rust. With the pieces now mostly clean of rust and paint, I set about removing the rest with a rotary tool and wire wheel. I also filed a few nicks in the metal down. before etching priming and then high-build priming. I then sanded back the primer ready for base coat and lacquer. Whilst they dried, I cleaned the other small pieces with concentrated degreaser and elbow grease and trimmed the rubber hose's protection fabric.
Once they had dried it was time to reassemble. I purchased some new rubbers, o rings, and some air filter material. I placed the air filter in the gap and began added parts to the booster. Once assembled the restoration was complete.

[@ghassanalfarra8935]

OMG, he buys junk that he doesn't need just to show us a repetition of the restoration process of the part he had already restored off camera .. Dedication level > 9000! Hat's off to you, Sir :)

[@RestoreIt]

Thank you Ghassan!!

[@GarthGoldberg]

I don't get this restoration in the first place. Dedication is there, but I don't understand why. You've spent so much time, and some money on materials, to cosmetically restore this brake booster, but you haven't replaced any of the internal parts that are likely to fail. A new unit is $300 and will be reliable. This unit may now look nice and shiny but may fail down the road. And boosters do fail, I can tell you from experience. Actually, I just looked it up. A new Ate unit for a Porsche (probably the same for BMW) is $201 USD. It makes no sense economically or from a safety perspective to cosmetically restore an old booster instead of just buying a new one.

[@josephknotts8618]

@@GarthGoldberg I was thinking the same thing. Like I get he likes to restore shit but it's kind of a waste of time. Who knows how long it will last. The diaphragms inside of those things are made out of rubber and with the outside of it looking that bad I can't imagine what the inside of it looked like

[@ghassanalfarra8935]

@@GarthGoldberg Read his description @00:20 at the bottom of the video, you'll find out that he has no plans on using this master cylinder for the very same reasons you mentioned.

[@douglasmorrison9098]

You are absolutely right as a matter of fact that piece of junk that looks SOOOOOO good is actually DANGEROUS

[@liamboardman8776]

Of all the channels to get a Fortnite sponsorship, I honestly wasn't expecting it to be this one. Still, you deserve it. :)

[@RestoreIt]

Thanks, Liam, appreciate it.

[@MrHBSoftware]

remove the circlip on the back of the master cylinder then blow some compressed air through one hole with caution while covering the other holes with your fingers...the piston will slide out, be carefull, and then you can easily replace the rubber seals and inspect the bore inside...if it is pitted then trash it...try it... here the replacement rubber seals are very cheap. you can clean anything brake related with alcohol only and for assembly wet it with brake fluid...brake fluid is hygroscopic so when storing calipers and master cylinders if you dont seal all the holes, air with moisture will get in and it will rust out on the inside very quicly, it can seize up in a matter of months..... edit: ok i just read the description now...sorry

[@dreadmireironbound8418]

I'm still here and I'm still 100% with seeing this entire restoration to the end

[@RestoreIt]

Too true Robert!

[@garybaris139]

Except that you cannot restore the booster diaphragm.

[@dewrus2153]

Another wonderful video...very therapeutic. I also really like the sounds (no music) in your videos. I read the description and know that you won't be using this booster/master cylinder but I would recommend that if you do, add a glob of good grease to the end of the pushrod prior to mounting the master cylinder on the booster...this will reduce wear but more noticeably, reduce the possibility of squeaking or creaking when pressing the brake pedal (ask me how I know...). I really like the paint/lacquer...seems to yield good results for projects like this. I live in the US so I'm not sure if I can get it here. I will have to look to see. Thanks again!

[@RestoreIt]

Thanks for the advice dewy I really appreciate it. I think Spraygunsdirect ship globally?

[@janetwelty]

I totally agree with the therapeutic compliment of no music, fast motion, and light work sounds. Job well done (video and craftsmanship)!

Waiting to see what you do with the interior. You’re also going to put a bunch of people out of business showing people how to rebuild their E30’s.

Just a little tip degreasers sometimes tend to leave a film behind so you may want to wash out the reservoir with very hot water and dry it out with compressed air. Brake fluid tends to not like other things mixed with it.

[@vansolo9794]

[@bmwe30club64]

Good Video Man.. just a quick question, should I change my breakbooster or just the master cylinder on my car, because when I pop the breaks from the inside, the car just moving and wont stop unless I use the emergency brakes.. so I removed the pads to see if they worn out, but they still fresh new..

I'm glad I stumbled upon your channel, you're doing a spectacular job, mate! But you're still not motivating me to restore my '01 740iL, LOL! It's not the motivation, of which I have plenty, it's the sticker shock of buying replacement BMW parts.

[@aldeacristian4582]

You should skip the basecoat and topcoat and just use a good quality 2k paint, like from Standox, Glasurit, Valspar/Debeer.

[@bernhardlist9359]

I always enjoy your videos since I am also restoring such parts BUT do yourself a favor and always replace rubber parts and seals since they willcame back and leak. Greetings Bernhard

[@garagemdoferri]

O cilindro mestre não é pintado. Deveria ter trocado os reparos do cilindro mestre. Aí ficaria novo.

[@tommichoo1]

Hi Restore it, may i know where did you bought your e30 brake master cylinder repair kit from? tried to look around but unable to find it. thanks. my e30 brake master cylinder has failed and looking for replacement. instead of replacing, if possible would like to look for repair kit.

[@aterack833]

It would have been neat if you took the diaphragm of the booster apart, but I’m kinda glad you didn’t

[@ninobenjamin9020]

With respect , What about the diaphragm? And testing it, and What about the master cylinder bushes and seals ? Without changing them all that cosmetic work is useless. .......

[@Falconhunter276]

Utterly fantastic. But, just to clarify, you are restoring a potential spare for the E30 after restoring the original part? The trouble with watching these types of videos, it tricks me into thinking I can do the same kind of thing in about 20 minutes. I have to consciously slow myself down and tell myself to take my time.

[@RestoreIt]

Thank you! And yes that's right. But my paint job is way better on this one so I'm tempted to do it again. This took a week in total, editing and all.

[@giovannipalumbo1179]

Why do you add crystal hardener to you solvent deep black paint iv checked the manufacture and it is not a direct gloss. It’s just binder and pigment normal solvent paint just need to add paint thinner 2:1 ??? Plus that hardener was designed for the clear coat

[@romanf5666]

there are two different things...if you ask a company to do such restaurations, nobody will do it, because too expensive and it makes no sense...but, if you do it by yourself and you are able to do it, perfect and you save money, as long as you dont count the hours...but who is counting hourse for a hobby? great work!!!

[@dennisp.2147]

With all that effort, I would have honed and rebuilt the Master cylinder and at least tested the Vacuum power diaphragm. I understand why you didn't, but a master cylinder rebuild kit is cheap insurance and then you'd have a spare.

[@mineshbhai]

Hello there. The link to E30 Stickers is broken. Can you please provide again...?

[@ilie1000]

i make the same with my brake booster but in short time i decide to upgrade my brakes in general so i choise 310 mm audi TT brake discs,e38,735 brembo calibers and double booster from e34.

[@Latruiequifile]

Great video. Just a little question: in the description you say you place air filter in the gap... Could you tell me which gap, please?

[@hafizimanap3909]

seems like you have everything except background songs,

[@superspice5659]

So many ads! Four and then a paid promotion. I don't mind ads but keep it to a minimum, I have ad block and don't use it on selected channels. Nice way to alienate your viewers. You have good content but it's pretty terrible.

[@MarkHyde]

Restoring old worn out parts may seem ludicrous when spare parts can be readily purchased but working to rebuild parts helps gain an understanding of process of manufacture and also allows practice of new skills. Also you're not possibly inheriting some else's mess, if you stuff up it's on you.

[@woodflors4u]

Very nice work. I really enjoy watching your videos. I notice you paint your parts. Are there any parts you have powder coated rather than paint.

[@MrGuvEuroman]

On the fabric covered hose, use a flame to burn the fabric ends/strays back gently then smooth it round with your fingers to give a perfect finish that won't Fray again 👍

[@areyouavinalaff]

no, don't use flame. paint the fray with 50/50 mix of pva glue and water, then wrap with small piece of cling film, then tape around the cling film to compress the fibres.

[@ninjamaster3453]

But where's the firewall gasket? He showed it crumbling I didn't see it replaced it new one made

[@geraldolmstead1335]

your work was good but your knowledge of what you were working on was not . The master cylinder had a rear seal leak this allows brake fluid to drain into the power boaster thus compromising the integrity of the diaphragm in side the power boaster unless fixed the whole project is useless.

[@matel1s]

If you have access to ultrasonic cleaner bath, put the fluid reservoir into it. You will be surprised by the result - it removes the yellowish color, so the tank will look like new.

[@ralfhartmann5050]

Very good videos. Probably the main brake cylinder ist full of rust particle. I would bye a new one.

[@IDmoody11]

I hope to see the e30 restored one day, good job buddy. keep up the good fine work!

[@RestoreIt]

Me to Jar, thank you.

i tought you had mounted the master cylinder upside down cause the vacum rose was on the right side but then you talked at the end of the video and i realized you're from the uk (or australia, i can't tell) and the break booster is on the left side of the engine lol anyway great video, you're a inspiration for me and my friends!

[@papwithanhatchet902]

[@chapelroadfarms1652]

Thank you for not adding any annoying music to these videos, and just keeping it simple.

[@HUBBABUBBADOOPYDOOP]

That paint job did come out super. Can I suggest that you make yourself a "tool" for your videos? Get a suitable sized cardboard box with lid, and a simple, cheap hair drier. Cut one hole for dryer, duct tape it into box, not pointed at the parts area. . Cut another slit for a vent. Only handle freshly painted parts with new nitrile gloves. Place your parts in drying box, dryer on HI for one hour. Let cool 30 minutes before handling The paint will be much more durable and harder when hot air dried.

[@RestoreIt]
