Gareth - PLEASE do a removal/install on the REAR hub assemblies on an F8X and HOPEFULLY get one that's badly rusted so we can see how you do it. Center locking nut, axle pulling and the demonic little placement screws that hold the rotors in place. The entire internet NEEDS this video...
@@fcpeuro Seriously.. I don't want to beg but I guess I am haha! The front bearing assembly I can handle because even if you strip the retaining screws, which I did, the whole assembly falls off, rotor and bearing connected, once the 4 x TP60 bolts are out. BUT... the rears are giving me nightmares and all the videos I come across are one nightmare after another - and virtually NONE of them address this. The rear assemblies "look" simple enough.. but they absolutely ARE NOT when they're rusted or seized. Help us F8x owners out!! PLEASE m_ _m!
As always a great video from you guys. This is the same procedure on pretty much any F2X and F3X with the M-sport brakes aswell. On the more "pedestrian" cars though, the brakes last longer and the hardware is stuck in there for a long time between disassamblies. Sometimes the locking pins are absolutely stuck in there and can actually bend when hammered out. So I recommend using a tiny bit of anti-seize on the tips and on the locking mechanism of the locking pins.
Since with this style caliper, pistons don't have protective rubber boot, It's a good practice to clean them with soapy water and tooth brush before pushing them in.
@10:18 BMW E9X M3 sighting. Change those rims to 359M Comp.Wheels. Two Tips: - Upgrade the brake lines to stainless steel brake lines while you have the brake calibers off. - For a car with more than 80k-120k+ miles, check the front wheel bearings for wear/noise by spinning them. The wheel hub has the bearings integrated in one piece that is a bolt on. If they need replacing, try to find OE replacements to save $$$$. On a BMW E9X M3, the BMW OEM wheel hubs are $400+ each. Rear wheel bearings are cheap, but are a huge pain since they have to be pressed off (slide hammer) and on.
Love this video. Just wanted to add to make sure you close the brake fluid reservoir cap 😂 I forgot this one time in my younger days and man oh man 😂😂😂 14:23
Great video, was going to pay someone to do it, but after watching I'm confident that I can do it myself. The link you have though takes you to z coated rotor kit. I've never heard of it before; do you guys sell the regular stainless, like the ones in your video? Thanks in advance!
Is it an absolute must to install 380 + 370mm brake discs on an M4 if it is just my daily fun car? No track days. I just cannot justify the cost of how expensive the 380 +370mm brake discs are.
As always, it's a great video. I have a question... Can I install M sport calipers on the 4 wheels with the same brake master cylinder of my car which works with single piston calipers?
Depends on the car, but generally yes. The retrofit kit from BMW for the M-performance brakes on F2X and F3X does not include another master cylinder. The pedal feel will change a bit though, it's slighty softer and longer throw - but there is plenty of power.
Every time I replace the brakes on my BMW E9X M3 they recommend that the brake pads and rotors be replaced. At the BMW dealership they charge about $5000 for the front and rear. BMW Indie Shops charge half that. But why can't the BMW brake rotors be resurfaced smooth, so you just need to install new brake pads?
URGENT !!!hello fcp ,I looking for bmw B48A20 engine workshop manual ,currently undergoes engine overhaul but is our first time and we have no excess for any bmw b48 manual ,hope you guy can help us out .really appreciate it thank you
Stretch bolts like head bolts, flywheel bolts, and these caliper bolts are all torque-to-yeild. This creates a high preload which helps them hold but it stretches the bolt when you get them up to their torque spec. That makes them more susceptible to fatigue so they should be replaced.
@@maxsam201 Depends on the thread type, diameter, and bolts metal composition but obviously it's 110nm/81ft/lbs since that's the torque spec. If you really want to know go put the specs into a torque calculator. A thing to consider is the expansion and contraction the brake caliper encounters from heat, especially during track use. Bolt that's have been previously stretched are more susceptible to backing out. People reuse them but the cost of a caliper coming off is way more than the $50ish it costs to replace all 8 caliper carrier bolts.
@@TheDudeAbides1776 I see no reason to continue with this. It appears that you are operating with some generic knowledge found on internet, and some of your statements make no real sense or baseless.
@@maxsam201 Dude, this is absolute basic mechanics. You don't need an engineering degree to understand torque-to-yeild bolts. Sounds like you're just too cheap to cough up $6 for a bolt.
