2001 Acura TL Q&A
2001 Acura TL Question: The brake pedal goes to the floor with constant pressure when stopped.
If it goes to the floor, it is not normal. Does it do it with the engine off. - ProfessorG
Another direction for you is to suggest to your mechanic to try a (little known) flex hose block off test...that will find this problem in about 5 minuets, or less!! If after hoses are blocked (pinched) the pedal is now high and firm,,forget about the master cylinder altogether...problem is air in system or cailper/brake pad not applying correctly. This will test 'REAR' brake componets as well...which are way too often overlooked! It works every time!! Learned this in a brake system failure diagnoses seminar years ago......test with engine running!!.... Testing the system is the key here!!! ...No it is NOT normal for the pedal to go to the floor! Rear calipers may be stuck on mounting bolts!!! - pushrod
