    I had braided hoses put in today along with, new grooved discs, and textar pads. Garage said they had them bedded in, all good I thought.

    Got out of the garage, pedal was kinda firmish, good braking power, didn't really go above 30-40 mph ..

    Get on the motorway, tap the brakes now and then, all good, nice and firmish. Now unluckily I suddenly had to do an emergency brake, from 85mph down to a standstill.

    Jesus christ, the brake pedal literally extended so far down it must have been like a cm from the floor !!!!! It was literally like I just had a pie replaced instead of pads !

    I was terrified so kept a stupidly big gap infront of me. The rest of the journey home and the brakes seemed fine but felt a bit sloppy now..

    Then I went along some dual carriage ways and now the brakes feel kinda spongy and just not really firm.

    I beleived the braided hoses were supposed to really firm up the pedal but tbh the rubber oem ones feel better if not the same.

    What is going on here? Why did my brake pedal go all the way down so farr ? Why is my brake pedal so spongy now ?

    Car is a e46 330d 2004 m sport touring. ( thought I'd put it in here as it's a general brake question )

    Update for people who may research this :

    Indy rang me at like 8pm and said do a proper brake bedding procedure. ( 8ish stops from 60 mph etc etc ) Had a bit of brake fade towards the end, good smoky brake.

    Parked up and left the car for a good 3-4 hours until all had cooled of.

    Hopped back in, excellent braking power from all speeds, very firm pedal, all is excellent

    Did you get an uprated brake fluid along with those new braided hoses? Uprated fluids bring out the maximum potential in braided hoses!

    Glad to hear all is well!

    He says I could have overheated the brake fluid in that sharpish stop I had to do.

    I think you've got just a simple air lock. If you had a fluid leak it would become visually apparent. "proper brake bedding" has nothing to do with the fluid doing it's job. It's merely to bed the pads to the surfaces of the disks.

    The brakes were not bled properly to begin with. In my humble opinion, of course.
    Start at the furthest point and work towards the master cylinder. Probably been done by a young mechanic who doesn't know how to do the job, or a "professional" who is rushing.

    Brakes are seriously important- Your garage is amateur.
    It costs HOW MUCH??!!

    Sounds like it wasn't bled properly.

    Another point.

    Engine was on and car was in Park. I pumped the pedal quickly a few times and it went very firm. Then when it went firm I pressed down and the pedal started sinking ...

    Tried this in D and the same thing happened..

    thats interesting...sounds like the vacuum in your servo isnt being replenished...check the vac line from the servo for cracks/splits
    what i've felt,what i've known
    never shined through in what i've shown.
