Brake Upgrade / Retrofit
Hello everyone im new here in the forum.
Recently upgraded my brakes to the red amg 6 pistons on my 23 gle 53 coupe (facelift).
However i dont feel right whenever i stepped on the brake pedal. Feels mushy and soft (like i have to step quite further to the floor).
ive bled the brake numerous times, probable 6-7timed already.
Question:
1. Do we need to do coding? I know BMW does.
2. Since its facelift version the workshop that i visited saying its on new software system.
Please does anyone has infomation on these?
All the help is greatly appreciated and many thanks in advance.
Regards,
ABS

Mushy brake pedal usually means 2 things.
Air in the system or a leak. Clearly if there is no fluid on the ground it’s not the second.
Coding will not help with anything in this case.

Thanks for the information.
Yes that's what I thought but done the bleeding too many times.
Therefore I don't think that's the issue.
Hmmm really lost at the moment.
Anyhow really thank you.

It's less reliable than pressure bleeding.
Working with an assistant to pump and bleed, can be good or bad, depending on "shared" technique. One slip and you have to start all over again.

First done at the dealership
Second done at reliable workshop
Third done manually with one person stepping on the brake pedal
Just ordered the brake hose.
Will be my last and only HOPE.

When you did the caliper swap did you cap the lines to prevent brake fluid from completely draining?
If the fluid completely drained out of the system, you may need to cycle the ABS pump via XENTRY to get it to bleed properly.
Normally, you don’t need to do this on non-SBC cars unless the system has been completely drained….
Also, I typically like to get some heat in the brakes and drive them for a month or so, and then do a final bleed after that.
It can be difficult to get all the air out of the nooks and crannies of those huge calibers, especially if they’ve been completely emptied or brand new.
Good Luck.

it was done at dealership for the first time.
I assume they would know how it's done hopefully.
they do mentioned now they have to manually bleed the brakes using pressure bleeder.
Yes will try driving the car around first maybe since I haven't driven it for a month since the brake upgrade.
If nothing changes then will try to do a complete rebleeding of the brakes.
Appreciate the helpp
