I’m having a problem with my brakes.
The brake pedal goes way too low. Not to the floor, like a completely broken master cylinder. It will stop me and also engage the ABS.

I replaced the master cylinder.
My brake pads are OK. There is no sign of brake fluid leaking around the wheels or anywhere else.

It’s better but not the way it should be.
The first pump is half way. The second pump is good. The next stop it's half way again.
It will still stop me and engage the ABS - but it's just NOT the way it should be.

 

Just wanted to add my end of problem story and hopefully it will benefit other members.

My mechanic is Cam Pettit (ten minutes away, lucky me!)

Low brake pedal / MC passed Cam’s bad MC test / even though, we replaced MC with new MC / still had the same problem, maybe just a bit better / bought Zoom Zoom’s 929 (great price and thanks ZZ) / brakes are worse / Pettit felt the only other component was the ABS system / Pettit rebuilt the ABS unit / brakes are awesome, better then ever which he attributes to the 929.

The ABS was full of 23 years of crap to where the system could not function correctly.

I try to keep the mileage down and generally only drive it during cold fronts here in FL.
Not driving it keeps the mileage down but is not good for brake systems and probably other reasons.
And it turns your tires into stones.

Hope this helps.
