Title: brake fluid change clutch ????
Post by: Edward James Morgan on March 22, 2017, 12:59:26 PM
Any one know by changing the brake fluid will make any difference and do you bleed the clutch with the same fluid .I got an easy bleed which i used successfully before but never bled the clutch and  Work your way round and do  the clutch last or do you bleed the clutch then start on the  wheels  after this is a complete fluid change .

I find the pedal a little hard i was wondering if i bled the system will it make any difference and feel to the pedal i got to admit i checked the fluid with a tester and it as water in the fluid so its need doing anyway  i have  not long bought the car so i assume it not been done for a wile

Brake fluid will not make pedal too hard but it's a good idea to change it if no record of being done.

Personally I would get as much old fluid out of resavoir as possible then refill with fresh before bleeding. Work from furthest away from master cylinder first and then do clutch after brakes been done. Again just my personal preference as to what way I do it.

For a hard brake pedal I would be looking at possible servo issues if it is unusually hard,on a normally functioning brake expect it to have some give when engine is running.
Try pumping pedal until it is solid then with foot on brake still start the engine up,you should feel the pedal creep down slightly.

Is it possible to change it over time just by replacing what’s in the reservoir, saving the need to bleed etc

No as you need to remove the fluid in the lines and calipers,you could have fresh fluid in res. It contaminated fluid in calipers that can cause brake fade. If you are going to do a job then do it properly is my thinking especially with brakes.

Check vaccum pipes aswell could also be a cause

Vacuum pipe to the servo a very likley cause of a hard brake pedal - they split at the ends and not always visible.

Best time to change the fluid is when your changing brake pads, as when you push the calipers back in you can open the nipples and push most of the fluid out of them at the same time rather than pushing it back up the system, plus you reduce the remaining fluid left inside the caliper.
