I can pump my brakes to build pressure and when I do it causes my rpms to go higher and if I hold down the brake peddle after pumping it makes a spudder sound from my [exhaust](/topics-exhaust/) when I let off and let the rpms go down it goes straight to the floor I’ve bleed my brakes and I replaced a steel line and I replaced front calipers there is no fluid visibly leaking anywhere’s Mechanic's Assistant: Just to clarify, what is the color and consistency of the fluid? And where is the location of the leak? There is no visible leaks and the color and consistency is normal Mechanic's Assistant: What is the make/model/year of your car? 1998 Honda Accord lx 2.3l Mechanic's Assistant: Are you fixing your Accord yourself? What have you tried so far? Yes I am I replaced both front calipers pads in the front changed out a metal brake line on the front driver side I’ve bleed both sets of front brakes I changed out the master cylinder and I tested the brake booster but some how I still can’t get pressure unless I pump the brakes the brakes still are somewhat functional and stop decent but they are still spongy Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? That’s it
