hey guys welcome back to the channel so if you recall a couple weeks ago i was doing
that budget brembo 17z caliper upgrade to the front so i fitted those to the front
i got everything to fit i had to do some trimming using those overkill engineering brackets so today
i gotta get to the back rotors and calipers so i've got the same matching 17z calipers for the
rear which are also used on the audi q7 and the porsche cayenne's and i'm going to fit them on
this car using rcf rear rotors you could also use isf rear rotors on the rear the reason why
i was using the rcfs was because i found a set of blank ones without the slots or the drilled
holes in it which matched those gs 350 f sport ones i used up front so stay tuned
so what we got today is these budget brimbo 17z calipers that i got on the rear here these are
basically like a dime a dozen you could probably find them on carpark.com for like 20 bucks each
plus another 20 for shipping which is what i really paid for these i think i got these for
60 bucks shipped from a junkyard in georgia the rotors i've got these are dynamic friction these
are the only ones i found on rock auto that didn't have the drilled holes or the slits on it so
they match those gs f sport front blanks that i got hopefully i can still get them in the
future these are the only ones i found and they were for the rcf and the gsf
all the stuff that i found for the isf all had drilled i couldn't find any blank ones the rcf and
the isf have the exact same diameter which is 345 millimeters that's 13.6 inches thickness on this
is uh 28 millimeters so they're massive rotors i mean they're they're not much smaller than
the 360 millimeter fronts so today we're going to get them onto the car i've got to do some
trimming of the heat shield and all that stuff behind there to get these rotors to get on there
and then once i do that i can fit the brackets and see how much i have to trim on the inside of
these it's going to end up rubbing a little bit of the rotor so you got to trim a little bit of
this part out and that's the only thing you need to trim for the rear not like the front with the
front was like full send massive trimming the rear is just slight trimming right here just to
get this down to clear the rotor over here we have those overkill engineering brackets for the rear
so these are the same brackets basically mirror images of each other for either side of the car
i had to pick up these bolts from belmetric so these were the 14 by 1.5 by 30 millimeters for
the calipers you can actually use the stock bolts off those calipers but i didn't get them when i
ordered those those use an odd socket anyways they use a triple square which is not a common one so
i recommend you switch to one of these allen keys or just regular hex bolts to fit anyways and then
i had to get some of these which is a 12 by 1.75 which hold the bracket to the spindle
and then you got to pick up a couple of lock washers to match so that's basically
all the hardware and the brackets you need to mount the calipers to the car
oh man that was a pain he asked to take that off so you notice i popped the rotor
with this little guy which is a basically just a 12 millimeter headed screw and then you pop
the rust and the corrosion so the rotor comes off but it looks like these springs and this retainer
kind of popped out of here which caused the pad to lock onto the rotor and it wouldn't let me release
that thing off of the freaking hub so i was able to just basically pry that thing out and get it
out so now i gotta fix that make sure all the springs are correct before i mess with it again
so now that we've fixed that drum parking brake we're going to have to start trimming
this dust shield so in order to fit this bracket which basically goes right here this bracket
bolts on right there where the factory ears are and then you'll see i have to trim the dust shield
right up to there this would be the new mounting point for one of the ears for the new caliper
and that's going to be the other one right there so i'm going to trim that all the way and i'm
going to cut that lip off this dust shield like i did the front and try to retain as much of it as
i can keep the dust from getting too much on the backside and provide some kind of cooling on here
so i got everything trimmed nicely i think it clears i didn't have to trim this bottom part
because it's already pushed back a little bit just to size it right down to here
then over here i think the rotor should clear
now yep clears on this side perfectly fine clears back here that bottom part i'm gonna
just have to bend it back a little bit with some pliers and it should fit perfectly after that
we just have to clean up all these edges with a flap disc
and a grinder just to make sure that there's not even too many
sharp edges on here and then and then just hit it with some spray paint after
that
so i bolted this down before i even shaved it and it looks like it might clear without
shaving it because right now i haven't gotten it fully tightened down yet but i can actually
spin this thing i'm gonna try putting the wheel on and see or i'm gonna tighten it all the way down
and we'll see how this fits once i put a lug on here just to see make sure there's good clearance
looks pretty clear it doesn't rub or there's clearance yeah
baby might fit without actually trimming it so at least that's a good thing i guess spinning it now
no rubbing no nothing it's actually got more clearance than my clearancing job on the front
so that makes my job a lot easier without having to shave anything on the caliper itself
man if it's not one thing it's another so with all my measurements and everything that
i've been doing for this i assume that we were going to clear with this caliper but i'm like
two millimeters i'm literally like two two and a half millimeters off the face of this wheel
right now from clearing so i'm gonna just for testing right now i'm gonna put a couple washers
just to see how they fit behind here and to know what kind of space they're about to run back here
just to make it work but yeah maybe i think when i was taking my measurements i was measuring the
old discs which didn't have the basically double thickness rotor because it's vented so
oh yeah that little washer trick did the job it's like a two millimeter or less clearance issue with
these calipers but oh yeah look at that clearance right there no clearance whatsoever even with this
little washer spacer so we got one little win as far as not having to shave these calipers
using these rotors i don't know if it's the rotor specifically or what or
the version that uh overkill engineering use i believe he used isf ones but i don't think
there was a difference maybe this manufacturer is just one or two millimeters smaller for some
reason i don't know but that's a good thing the bad thing is i can't clear these thinking
wheels over here what i'm gonna do is i think this face i'm just going to take a
palm sander a flat palm sander and try to sand it down just take a couple mils off of there from
sanding before i powder coat and all that so that way i don't increase the thickness too much and
hopefully that's good enough to clear these wheels right here but that's the only issue i've got so
far right now but i'm just happy i don't have to shave anymore caliper hey guys thanks for tuning
in all the way to the end of this episode so i'm gonna go ahead and finish the dust shield clean up
and flap this thing and get rid of all those edges off camera along with the other side i'm gonna
do that off camera just to get the fitting and getting all that dust shield stuff done as you can
see this project for the 17z rear brake caliper went a lot faster and a lot better than the front
just because i didn't have to shave down the caliper the only problem we ran into was getting
that wheel to clear which i didn't expect because i thought there was plenty of clearance but
i didn't account for the double thickness of the rotor being vented and all that other than that we
just got to put a one and a half millimeter spacer so don't forget to stay tuned for a future episode
i've got my powder coating equipment and powder coating stuff coming so we'll go ahead and take
a shot of powder coating the front and the rear calipers on this car and get them reinstalled
other than that i just want to thank all of you guys for tuning into the channel over the last
year year and a half as i started concentrating on getting better content out the channel is steadily
growing i just want to thank each and every one of you that keep on watching my videos and

making youtube videos these days that it's hard to get a lot of people to tune in and subscribe but
i just want to thank you guys for all tuning in and leaving comments and giving thumbs up and
and all that but uh don't forget to leave comments leave questions i try to answer everything that's
asked on all my videos you know if you have a question just go ahead and ask i also include
a lot of information in the description box of all my videos to help you guys whether it is
buying the product or instructions on what to do or additional information that i've discovered
but anyways i just want to thank you guys for tuning in and i'll talk to you guys next time
you
