    1991 LC70 PZJ77 (Load sensing for rear brake)

    Happy and impressed with your response. Now I was understanded exactly how LSPV works, [the higher the speed, the lower the pressure when braking with maximum force] and when braking softly, the pressure in the rear cylinders does not drop and the pressure is at the rate at which the lever is...

    Hi Ralf Excuse me Ralf I've tired you out with me - I lowered the LSPV body and also raised the jack in this case the fluid pressure should rise but the brakes are still the same. - when raising the LSPV body and lever (tie to the car body) because the jack when it is at the maximum limit in...

    Hi Ralf 🌷 I have a problem with raising or lowering the valve body. Does raising the body lower or raise the pressure? Now the valve body is raised .

    ● Hi Ralf, how are you? Excuse me for bothering you. 😊 ● I fixed the rear cylinder, changed the brake fluid and blew the air out of it, checked the brake pads and tested the LSPV. ● First, I lifted the shackle from the axle to the body of the car and tried the brakes at a speed of 30 km/h on...

    1991 LC70 PZJ77 (Load sensing for rear brake)

    Hi Ralf how are you? I meant the brake warning light. You told me that you suspect my car has a (brake sensor). How do I know if my car has a brake sensor or not? Because I don't know. I forgot to tell you that the fluid level is good and the brake booster is good. I think it's because of...

    I also have a dim brake light, is it due to the brake fluid leaking from the rear brake cylinder?
