i have just been to buy some brake fluid,much as i know i need dot4 i dont know which one.Comma bottle says synthetic the mobil bottle tells you nothing,the halfpords link for the brake fluid says suitable for all drum and disc brake systems and no mention of glycol or synthetic,very confusing to the average joe who just wants to top it up. I have a jelly ...

Here is a standard procedure. You may need to use a vacuum hand pump to 'prime' the master cylinder. I have encountered the issue you are describing and the luxury of having a mighty vac to pull the brake fluid through the system. Once the master cylinder is primed, it becomes much easier and you begin to get traction on getting the air out and having the ...

Someone else might have something better, but I'd probably just use a portable carpet cleaner with regular solution which goes in it. It should leach most or all of the brake fluid out of the carpet ... I doubt you'll get all of it out, but it shouldn't be too big of a deal. Clean it a couple of times and you should be golden. If you don't have the ...

The bleeding procedure is the same as it would be for a hydraulic brake system. There is a nipple on the master cylinder to bleed out fluid and air, same as a brake caliper. Pump the clutch to build up pressure (keep clutch depressed) Open the nipple/valve on the master cylinder Allow fluid/air to escape from the nipple/valve Close nipple/valve on master ...

Whenever you break the brake system open, you need to bleed the entire system. This ensures no air is in the system, nor any contamination. Besides, brakes don't usually get bled enough anyway. Brake fluid should be completely changed every 2 years at a maximum (even I am a failure at keeping up to standard on this). It realistically doesn't take a lot of ...

Most people don't do the whole system, but as someone else said the brakes will most likely be spongy and get more so as time goes on. The other thing you have to remember is that even a tiny amount of air will start to breakdown your fluid And most people never change their brake fluid. So it's the start of the system getting slowly worse It's your ...

I would have the front wheels bearings checked. A bad bearing can cause sensor misalignment and the ABS to activate. You may also have an issue with the power brake booster. The booster uses engine generated vacuum to assist with pedal effort. A leaking vacuum line may be reducing the vacuum and increase the pedal effort required to stop.

tl dr - Mixing Brand X fluid with Brand Y fluid is of no consequence, as long as you are mixing the same grade of fluid (DOT3, 4, 5, or 5.1). In order to be rated at a given grade, it must meet the prerequisites of the grade. This has to do with wet/dry boiling points, not who makes it. With that said, you can mix DOT3, DOT4, or DOT5.1 together (each of ...
