Why is my brake pedal mushy after a service?
Brakes require being pressed almost to the floor to generate force after a shop visit, leaving drivers with a dangerously soft pedal. This stops drivers from braking reliably and risks a total loss of stopping power while driving.

In their words
Unedited, grouped by where they were said, most upvoted first within each place, each linked to the thread it came from.
“I replaced all the hardware, wheel cylinders, shoes, drums, and did a brake fluid flush with brand new brake fluid. But the brakes still feel squishy.”source ↗
“With the car off, the pedal is soft at first, but firms up and stays firm after the first pump. With the car on, they only firm up after pumping a little bit.”source ↗
“The only other think I can think of is there would sometimes be fluid coming from the bleeder valve threads, but I'd usually tighten the valve down before the other person let go”source ↗
“1978 f150, no fluid reaching the rear drums. Got the front disc brakes bled on a new master cylinder with separate reservoirs. Why is the pedal mushy? Do the rear drums have to have fluid for the front brakes to work as well?”source ↗
“After that the brakes had to be pressed a lot for braking force to be applied, almost touching the floor.”source ↗
“I wanted to get a second opinion here and wanted to know if they are right, or does anyone know if it is some other issue?”source ↗
“Swapping over my ABS pump as the motor has failed (code 5DF0 and 5DF1). I trust myself to do the unit swap but I don’t trust myself to prime the system with INPA properly.”source ↗
“Can I carefully drive to a garage roughly 2 miles away and have them fully prime the brake system for me with a power bleed?”source ↗
“My usual local garage quoted me £2500 for the job and said the pump was over £2k alone and they won’t fit a second hand pump”source ↗
“now my brake pedal goes all the way to the floor and and when I but brake fluid in it vanishes the car didn’t have any braking problems till we put the new piston/ caliper on and no we didn’t not bleed the brakes”source ↗
“Would fluid come out of the master cylinder fitting without pumping? Or do I need to pump the pedal.”source ↗
“After the work was done, the brakes felt exactly how I wanted them to, the pedal was firm and braking felt great. However, after a couple of days, the pedal gradually went back to its original softer feel.”source ↗
“After the work was done, the brakes became much worse. The pedal went almost all the way to the floor, and there was a significant delay before the car actually starts braking.”source ↗
“I had the rear discs, pads, calipers and brake hoses replaced on my 2003 Golf 4 1.6 16V. Now I have to press the brake pedal much further to get the same braking performance as before.”source ↗
“even when pressing the pedal just slightly (around 1 cm), the car seems to brake much less than it did before. I now have to press the pedal considerably further to achieve the same braking force I used to get with much less pedal travel.”source ↗
“It is on the softer side but not too spongey. I have to press the brake pedal more than I used to for the car to brake at least a bit”source ↗
“I felt like it took longer for me to brake than normal.”source ↗
“I’m just worried because it took me longer to get my car to a stop and the pressure I need to put on the pedal feels different.”source ↗
“when I first took it for a test drive, the brakes are super touchy and when breaking hard there’s resistance on the pedal. At my hardest break I’m still at least an inch from the floor.”source ↗
“there’s still a wall that you hit about 3/4 of the way down where resistance increases significantly and feels almost over pressurized.”source ↗
“since the day i bought it the brakes have been a little squishy”source ↗
“my pedal went to the floor while driving down a mountain road and triggered all my ABS/VDC lights again”source ↗
“Came to pick the car up and it still had ABS/VDC error lights on start up and the brake pedal still went to the floor.”source ↗
“So far i'm in $2,300. HELP”source ↗
“Now I have to press the brake pedal much further to get the same braking performance as before.”source ↗
“even when pressing the pedal just slightly (around 1 cm), the car seems to brake much less than it did before. I now have to press the pedal considerably further to achieve the same braking force I used to get with much less pedal travel.”source ↗
“I also noticed on one of the newly installed rear brake discs, there is a circular groove running all the way around the disc.”source ↗
