Soft Brake Pedal #2

[Jason P-S]

Hi all,

MB (Sandown Guildford) advised all four discs and pads should be replaced amongst other items . The car was booked in and 5 days later! the car was ready; the braking however on the drive home didn't fill me with confidence as the pedal was incredibly soft to the point of almost reaching the floor. I returned the car the following day and the tech advised the brakes were bled/car test driven and I was "good to go" apparently. There was no improvement but due to work commitments I had to leave.

I will be returning the car for further investigation but in the meantime, I would appreciate any advice on either possible self checks or seeking a second opinion. I felt the tech at MB was simply paying me lip service to get me on out of the showroom.

Thanks

Give it a few days, with everything new, id see if they “bed in “ after a bit of use

Hello and welcome

All 4 brakes needed replacing... profits must have been down...

It is likely that the new pads and disks will take a little time to bed in but a soft and spongy pedal denotes air on the brake system.

Monitor it and take it back if it doesn’t improve.

As above. Give them a bit of time to bed in. If they are still bad after that, then it could need a brake fluid change, especially if the old pads were very worn.

Pushing the pistons back into the caliper pushes all the old fluid back into the system, which can give a spongy pedal.

Thanks, again the tech advised the pads were already bedded-in. Surprising really as the year drive was less than a mile.

I collected the car Tuesday so will allow a couple more days as you suggest.

Thanks all, appreciate the prompt responses.

If we picked up a brand new car with poor brakes we wouldn't accept "give it time, it'll come right", I don't think you should here. There's a problem that needs sorting.

But I suppose you could always carry an anchor to chuck out of the window if they aren't stopping you as keenly as you would hope.

I m o it’s air related

Does the pedal travel get shorter with a second quick pump? If it does there is almost certainly air in the system.
