brake pedal goes to the floor on my 07' KIA Spectra5 SX (w/ABS)
What is your question?
Driving and went to apply the brakes and my brake pedal went to the floor but my vehicle did stop! I replaced the brake rotors as they have been turned prior over the years and were to close to min. specs. I also installed new brake pads and master cylinder (I did bench bleed the master cylinder) and proceeded with bleeding the system. My pedal still goes to the floor? Though I did notice something when bleeding the brakes... all the calipers gave me a good pedal after bleeding but the right front, as it just did not feel the same? After bleeding the brakes I had a good pedal until I started my vehicle to back out of my driveway! This is a very well taken care of vehicle with 125,000 miles. I am a retired certified auto technician that has not wrenched in 20 years and my vehicle has me stumped. I am almost ashamed to even be sending this but it is what it is and I do not have a problem asking for help.
How long has your 2007 Kia Spectra5 had this problem?
RepairPal Certified shops can diagnose and repair your 2007 Kia Spectra5. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Make sure the calipers are 'sliding' on the mounting bolts - occasionally the mounting bolts get seized and that allows too much caliper piston travel which transfers / results in to too much brake pedal travel .. As you know - sometimes it is difficult to purge all air from brake system .. Bleed all again...
Now .. Using a clamping tool - you can pinch the rubber flex hose closed at the caliper - then test brake pedal travel - you'll find the culprit!
I retired in April - it doesn't take long at all to get behind when you're not doing it every day!
