As a machinist of 32 years I would not use loctite red, I would use blue. Red will not allow you to break it unless you have a good impact gun. Blue is standard on this job. I've done at least 50 fwd brake jobs. Anyways the fact that you cut the sheilds and no one shows you this, is awesome man. I'm piecing my kit. I got those calipers for 102 a piece. I have a 2015 st2 that defines my life. Hoonigan, in honor of Ken Block. That's why we have this car. Anyway thanks again. My car will be able to stop on a dime and give it back

[@dham99]

yeah most just remove the dust shield, but trimming it is a good touch and allows you to protect the front wheel area from all that dust. I have NEVER used red on any parts of my cars or trucks... if the blue backs out, you either didnt have enough for youve got other issues lol... In fact, on the caliper bolts, ive never used loctite. They have never backed out and since i track my car a few times a year, i swap pads/rotors/wheels/tires each time at the track before racing, so im already inspecting things. But a little blue loctite never hurts for sure

[@a.oakley983]

Where did you find the calipers for 102ea? I’ve heard this a few times but never had luck finding them

[@keithr5591]

​@@a.oakley983i actually just bought a pair on rockauto for 100 and 150 bucks(core fee for rh side) . They're remanufactured but have the same warranty as new from ford.

[@Q8TwinTurbo]

Thanks for the install walk through. The weights of the calipers and bigger rotors of the RS were surprising to be lighter than the stock ST calipers and rotors. Great video.

[@bigkev10101]

Awesome job. Everyone else has been saying that the wheels have to be changed to work. The 5mm spacer and using my stock wheels is the reason I will do the change. I have a 2018 ST1 with only 7k miles. New tires and wheels are a huge cost to add to a brake upgrade. So now I plan on doing the same upgrade that you did. I travel a lot for work and this is my fun road car. Mods: torque solutions shift plate, Ford carbon shift knob, curt trailer hitch, dash cam, auto darkening rear view mirror, Steeda clutch pedal spring, sound delete.

[@JrsGasolineAlley]

Sounds like an awesome car, good luck with the modding.

[@anthonymalfino1]

This is an excellent video man. I have an st2 an zee brakes are just red but the same. Just got me brembo calipers for 102 a piece from rockauto

[@dham99]

the weight savings is big, i dropped 8lbs per wheel by going with RPF1s (18x9), so these are another 6lbs less in the front on each side...thats considerable. The looks are nice, but where i can personally vouch for the need for good brakes, the ST stock braking system is terrible if you track your car hard or run it on the back roads more than a few consecutive hair pin corners...the single pistons just cant handle the heat and they fade fast.. even with good pads. You can get this set up fairly cheap now and the crazy thing as you stated, theres not much to swap over minus the rotos and brake lines in the front (rear RS and ST are identical). good video..and yeah you prob dont need this if you never track your car or really run it hard in the twisties...but if you can get a set for a good deal, do it! While you're there, flush the fluid and get some higher temp brake fluid (like Motul600 or something)...thats your next factory weak point...boiling the brake fluid.

[@Maga28DS]

Jr's Gasoline Alley, firstly thanks for the tutorial and install, good job! Really good upgrade. could you answer me some quick questions or doubts? I have a Volvo V40, it's the same chassis of the ford focus mk3, but your stock calipers looks the same of mine. it's possible to install this brakes on my V40? the mounting it's the same, plug&play? and other question, your rims are 17'' one's?

[@FastlifeTodd]

Pedro Miguel Silva I recently bought these to test fit on my 2013 Volvo C30 Polestar which is the same chassis as the Focus and Mazda 3 and of course the S40/V50

[@anthonymalfino1]

I think this an excellent video. I'm gonna do this. I have stoptech and they suck. The cast iron is better any way. Look in any race forum. Thanks again sir!

[@JrsGasolineAlley]

Nice, good luck

[@michaeldaye7889]

Just ordered this kit off rock auto except the caliper hardware kit. Had to second hand source due to them being out. Only ran about $700 with tax which beats the $1000 price the “kits” are shipping for from summit or jegs

[@phillwaller]

interesting that you mention the unsprung weight affecting the suspension. given that the weight isnt technically "suspended" does it affect the suspension. I'm all for saving weight but just wondered if you had considered that. Great video either way though dude. The calipers look amazing.

[@JrsGasolineAlley]

How is it not technically "unsprung weight"? A brake caliperr is on the suspension so it is for sure unsprung weight, just the same as the hub, the wheel, the tire, or in short everything not a part of the suspended chassis.

[@RSKev]

totally worth it, would love to do it with mine but only if I could find a red pair! I know they only come in nitrous blue lol

[@JrsGasolineAlley]

Paint them. They sell these calipers in an unpainted silver so you could then paint it from there.

[@loganloganloganable]

Or get willwood

[@KonaFocus]

Just a note for us pre-facelift folks. Ford makes no mention of dust shield interference on the larger rotor if you buy the kit. If you have a 13-14 ST, you will need to order 15+ dust shields. I an unsure if RS shields will bolt to the ST knuckle, but newer ST shields fit as the knuckle is the same 13-18 for the ST.

[@yomny7713]

What size flare wrenches are we talking about?

[@martynj-c4965]

Do you know the actual colour name or code for these calipers? Thanks

[@jwb4bb]

I was holding my breath when you cut the heat shield, I was afraid you were gonna accidentally slip the die grinder into you sexy new caliper? Have you taken these on track? If so, how did they do?

[@jessebudelman]

When i do my RS brake upgrade I’m doing RS knuckles and adding the Ford Performance gloss black standard 18’/19’ RS wheels..or see if i can find an aftermarket wheel that’s lighter...not sure yet

[@jessebudelman]

Taken from Damond motorsports page. New knuckles on our shop Focus ST, borrowed from the Focus RS. Left is ST vs Right is RS. Lots of minor improvements in better suspension geometry, resulting in improved handling and steering. The hub center is moved upward from the lower ball joint mount. This allows for a major improvement in roll center. The lower ball joint mount is also moved forward more of the hub center. This adds caster. The mounting point for the steering tie rods is shortened. This results in quicker steering. The steering rod mount point is slightly lower compared to the hub center. This means less bump steer when lowered. The knuckle shaves a bit of weight in that little excess casting material is found, about 1lbs each. There’s also a tiny bit of negative camber added as well. When you’ll be going up against Civic Type R’s, any little bit helps. If you’re looking to make your ST or RS into a handling machine, feel free to hit us up! #damond #damondmotorsports #tracktested #tracktesteddrivertrusted #fastishard #fordfocusrs #focusrs #fors #fordrs #ecoboostrs #fordfocus #fordfocusst #focusst #fost #fordst #ecoboostst #ford #fordperformance #ecoboost #suspension #suspensiongeometry #knuckles @ Damond Motorsports

[@JrsGasolineAlley]

Smart to add the RS knuckles

[@jessebudelman]

@@JrsGasolineAlley how’d they hold up? Just got my RS brakes finally. Any chipping of paint over time?

[@CoreyThaemert]

i just got this kit and was wondering what issues or what made the bleeding process tougher? also i notice two bleeders (one on the inside and one on the outside) did you bleed the inside first then the outside?

[@JrsGasolineAlley]

If you Google the Ford Performance brake upgrade kit, it will have the instructions or just watch that part of the video...

[@Josip8899]

Hello there, I have few short questions for you cause I'm thinking about buying STD here in Europe. 1. Which 5mm spacers do you use and does it need changing bolts, do they need be longer for that 5mm spacer? I will probably run ST wheels as winter setup. 2. Do you have to do something about oil pump or something like that when changing from OE to Brembo brake calipers? I mean, do you have enough braking fluid in system? 3. Is there any problem in clearance except cutting that heat shield? 4. Plug 'n play? 😁 Thank you. 🙂

[@JrsGasolineAlley]

1, no need for different bolts. Use the spacers linked in the description. 2, the master cylinder is the same on a RS and ST so no issues with this vs the original brake caliper 3, only mod needed is the heat shield. 4, yes plug and play

[@Josip8899]

@@JrsGasolineAlley thank you very much, respect for great answer! Cheers!!

[@aca2081]

One question, did you notice anything regarding the brake bias? Since you got bigger brakes on front but left the rear ones stock.

[@JrsGasolineAlley]

Same master cylinder, same hydraulic volume so the brake bias and power will be the same. This gives higher heat resistance, better brake feel, increased friction coefficient with larger pads. Also you can just swap caliper carriers and go larger on the back too.

[@dham99]

what people do is they buy the Mazda5 rear caliper bracket (C2Y6-26-28XA if i recall) and then can fit the slightly larger RS rotor...same pads, brake lines, etc so no need to swap those parts.

[@iR800lbGORILLA]

Can you use OEM ST brake lines?

[@user-fd5sv1qr7e]

Hi. Can you give the catalog number to the brake disc? And the question of mounting to the hub (5x108) is correct? Thank you.

[@jamesmorrison1775]

Can you reply with a link to what spacers you run??? I've heard that the RS brakes won't clear stock ST wheels

[@JrsGasolineAlley]

That is true. I have two videos with links on this topic. 5mm Spacers: kzbin.info/www/bejne/l5yZpI2Kas2Br8U 20mm Spacers :kzbin.info/www/bejne/ipTYcpuOaLZnfs0

[@nateonfireball]

Do you know what size spacer is needed with the premium wheels?

[@Bladesje]

I wonder the same

[@xuk]

Premium wheel won’t fit, no matter what spacer

[@rinXneko]

What is the width of that spacer?

[@SAVAGEMADNESS]

top! top! Your previous rotors size are 320mm, or 335mm?

[@dham99]

if he's a later 14-18 ST, he has the larger rotors. Only the 13-late 14 STs had the smaller rotors (and caliper brackets)

[@horsebrother]

whats the rotor size running with brembo caliper

[@JrsGasolineAlley]

The RS Rotor 13.7"

[@user-fd5sv1qr7e]

Please tell me the answer to my question. I have a Ford Escape II. It's based on Focus. I don't have enough regular brakes. There is a desire to install a reinforced Brembo kit for RS. I have three questions: Is there any effect from this kind of work? No need to intervene to replace the main brake cylinder and vacuum booster? Can you tell me the size of the rear tomosal disk RS? Thank you, I will be glad to answer.

[@choose6174]

What would be the negatives of removing the heat shield outright?

[@JrsGasolineAlley]

Heat would not be shielded from all the rubber boots and brake hoses inside the wheel well.

[@choose6174]

Jr's Gasoline Alley Okay thanks for the response!

[@yomny7713]

Did you add spacer to the rear for even look? Enough turns on the lug nuts to be safe?

[@JrsGasolineAlley]

I did. 3mm and 5mm work with stock wheels and these brakes on the stock studs

[@Czoix_Polska]

Minimum spacers is 5mm ? Pins are stock ?

[@JrsGasolineAlley]

minimum spacer turns out to be a 3mm, I put a video up on that. However, if you want a pair of 5mm spacers to let me know, I have a set that I used for this video that I am looking to sell.

[@Czoix_Polska]

Jr's Gasoline Alley ok thansk! I Have 3mm spacers. Instalation in this weekend. I have one question for you. Bolts for crossover is the same ?

[@C.P.C3719]

I have a Ford Focus 2016 SE. Will they fit on my car?

[@JrsGasolineAlley]

Yeah

[@lonefocustv9251]

Saves more than 6 pounds, with the bracket also being removed entirely and they are heavy buggers!

[@Dar3D45]

He weighed the caliper with bracket and pads still installed/attached so its 6 pounds per side.

[@Hobbyzocker100]

If I want to install this brake system, will the 17-inch winter rims still fit on it?

[@JrsGasolineAlley]

Maybe. Most 17" wheels don't fit, but there are a few. Check some of the guides on Focus forums for more info.

[@FocusRSFloripa]

Hi... Are 18" wheels certain that they are compatible? I have 2Forge 18" 8 wheels and I want to do this upgrade.

[@patricksoler]

It seems like you really rushed over the brake bleeding part. I just bought this kit and plan on installing it this weekend. Taking off bolts is easy, but when you got to bleeding, there wasn't much coverage.

[@JrsGasolineAlley]

So that didn't get as much focus as you would have perfected. I hope you got yours taken care of.

[@josel2690]

Will these fit on a fiesta st?

[@JrsGasolineAlley]

I don't believe so, but maybe with an adapter!

[@joshhowells1097]

Can you get this for Ford Fiesta titanium ??

[@JrsGasolineAlley]

Unfortunately not.

[@lindebr]

What’s the cost of the RS brakes and rotors?

[@JrsGasolineAlley]

Not too bad. Check Rockauto

[@jamers99]

How come your stock calipers are not red? Don't all ST's come with red calipers?

[@JrsGasolineAlley]

Only ST with "premium" wheels get red calipers

[@bacchusthompson5834]

Nope... I have a ST1 and no "Red" calipers for me ☹️ I got paint though 😁

[@Bladesje]

what about the rear? and parts costs

[@JrsGasolineAlley]

Rears are to be done this summer.

[@MrFinality69]

Rear rs brakes are identical to the st rear brakes

[@mikestepan7478]

Debating these or a wilwood

[@zackmandarino1021]

I'm doing these because pads and rotors are way cheaper and the front and rear is 1600 less than front and rear for willwood so unless your going to be heavily tracking it and adding like 300 hp there is no need for the willwoods

[@MrFinality69]

Will willwoods fit with out the spacers?

[@invalidusername_5101]

Not everyone has it done ?? Lol

[@JrsGasolineAlley]

Weird flex but ok
