REBUILDING A CHEAP BMW M5 COMPETITION | PT 3

[@dougieturnbull8830]

I’ve had the same problem changing brake fluid on a couple of BMW’s, it was air trapped behind the calliper pistons. I had to push the calliper pistons back with the bleed valves open to remove the air, also try pumping the pedal at the same time as the diagnostic tool is working the abs pump, this worked for me

Hey Mat, I have some experience working on BMWs and would like to help you diagnose, here are some ideas to start: - The amount of points you bled the brake system from; how many? Though I'm unsure of F90s specifically, from what I've seen on an F10 M5, you need to bleed each corner from two seperate holes: one to bleed the inside pistons, one for the outside pistons. - Try compressing each piston fully while bleeding it, this should help get trapped air out. - Some specs of the newer BMWs lock out the gear lever if the driver door is open, sometimes even if just the seatbelt is off. Due to the airbag system and the restraint system being tightly connected, I suspect there's a slim chance airbag errors could lock you out if it's one of the cars that check if the seatbelt is off. It's unlikely but certainly a possibility i guess - Pump the brake pedal during ABS bleeding - I can hook you up with a very recent & clean version of ISTA if you want to try the ABS bleeding procedure with that. cheers

[@robertbyrne781]

We do this bleeding procedure in work with vans, you have to connect a pressure bleeder to the brake fluid reservoir with atleast 1.5 bar of pressure, and bleed each corner with the computer while someone pumps the pedal, you need someone to pump it to help physically push the fluid out of the abs pump as it activates the solenoid valves internally, hope this helps matt 👌

[@kevin_bailey158]

Usually you need to have a pressure bleeder regulated to 2 - 3 bar and use the diagnostic equipment to activate the ABS pump valves and someone sat in the car pressing the brake pedal all at the same time and you need to start at the furthest wheel away from the brake master cylinder. Love the vids Mat just wish they were uploaded every day lol

This is the official mercedes benz way on some of their cars, pressure bleeder set to 2-3 bar, bleed nipple open, keep pumping the pedal with the nipple open, all of a sudden you get extra air bubbles out

On BMs if you empty the overflow reservoir and allow air into the abs sensor / master cylinder it has to be refilled by BMW using a specialist high pressure system. In the Haynes manual it warns you about this if you're doing the brake bleed. You've got to make sure the reservoir is always full. Welcome to working on BMs! Great video as usual Mat, your old man is a legend as well. Congrats on the million subs too. Well deserved. Love these videos.

[@deanasser8813]

Check to see if the master cylinder piston is not stuck inside the base of the master cylinder, I have experienced this if the brake pedal was pushed with calipers removed or no fluid, it may not have a return spring in the master to push it back, it's easy to tell if the pedal has little to no resistance at all. Worth a shot! Loving your videos bringing these beasts back to life!

[@davidsibley4857]

When bleeding brakes that have been apart like this I found using a different colour fluid helped me track when new fluid was pushed through, ATE Super Blue was fab for this and you could alternate from yellow to blue each service. Also an Eezibleed kit is good for pressurising the system, I use about 25psi. You need decent pressure behind it. The computer is pulsing the ABS solenoids to try and push the fluid (and air) through so having pressure in from the top assists this.

Be careful as the OPFs are located in the link pipe of the exhaust system and not in downpipes on M5 F90. If you intend to replace the downpipe only, you will loose the pressure connection and keep the filters, which may cause some damage.

[@mista5796]

Matt, you can get a non return valve (aka one man brake bleed kit) to put over each bleed nipple. Start with the rear wheels first, then move to the front. Because air has become trapped in the ABS module I think you’ll need a pressure bleeder to force the brake fluid through the ABS module under pressure. Have someone topping up the level in the reservoir as required. Someone else pumping the brake peddle and a 3rd person checking the tube connected to the non return valve. Make sure you put fresh fluid back in not the old stuff. But before trying to drive it, replace all the airbags and anything else that got damaged. Clear all the codes and it should be good to go. BMW’s are fussy with their interlinked systems. If it detects safety issues it won’t let you drive Good luck dude🤞

[@SuperBikerGP2T]

get yourself a pressure bleeder (maximum 2bar) when you bleed the brakes on these if the system has been apart you need to vent the dsc unit. this is done in 2 phases. 1 - when bleeding with the pressure bleeder on get someone to also pump the peddle every 3 - 6 seconds and then the second phase is to pump the peddle with the bleeder switched off and the bleed nipples closed whilst activating the dsc pump. this needs to be done for each axle (diagonally split system) so do this on the nsr and then the nsf. then finish with a normal bleed cycle going from nsr-osr-nsf-osf and your peddle will be hard again. it’s near enough impossible to vent an air lock without a pressure bleeder on these. fyi we use ista for this function so I can’t say your diag system has this function. And I’m a Bmw senior tech. 👍

[@Josh23_]

@MattArmstrong I worked in a garage for a few years and we had this issue come up on an M5 where the brake pedal was recessing down to the floor. We found it was the master cylinder that was faulting. A replacement was put in and 4 new brake pads were added but before they were added, they were put onto another M5 and were bedded. Air in the lines should give you a 'softer braking' feel, a worn or bust MC will give you a sinking feeling which Is what you're experiencing by the looks of it. I'd eliminate the ABS pump from being the issue as it's correctly bleeding the lines. May be worth taking a close look at your master cylinder and seeing if there's anything visible. You can pick them up second hand for anywhere between £60 - £400

I'm a very late comer to MA but did see Derek at VGG do the same thing. It's mad but you feel a sense of pride yourself watching a channel grow and reach 1M subs.

I'm not even a massive car person but the joy on your face when that started was awesome! I build computers, which is child's play compared to this kind job. Gonna watch PT4 straight after this.

The nice thing of working on BMWs is that the engineers have taken care that for disassembling -say the waterpump- all the bolts and nuts are the same size (say m6). Actually there are only a few sized nuts and bolts to (dis)assemble the car. And most of the nuts and bolts are relatively easy to reach. On older cars i had almost no issue to loosen bolts and nuts, even after many years of use, so yes, i loved working on BMWs.

Amazing project mate! Can’t be sure but on a Mercedes old sbc system in order to bleed the brakes the engine is was needed to be on and running, otherwise the same was happening. But giving this is pretty much a new car who knows 😅
