Geely emgrand, how to clean the accelerator brake when it fails?

Hello, my friend! No, no, you said the brakes were too heavy after clearing the throttle! If so, it's you. When removing the throttle body, put the vacuum tube of the brake vacuum booster pump on the intake branch pipe. I dropped it. Or the vacuum tube of the brake vacuum booster pump is blocked. I hope my answer can help you. Please feel free to contact me if you have any questions.
