Hydraulic Brake booster question

guys,

I have a question concerning the hydraulic brake booster in the 2011 TRD Offroad...

What is this?



I'm planning to flush my brake fluid this weekend and was wondering what this is and if it something that I should replace.

Thanks for the info

 

My Japanese is not real good and the French I can't read but my guess is it is an accumulator and probably has a very large spring inside and they are telling you not to take it apart. It gives the hydraulic boaster system a kick if the engine quits.

 

cool, thanks

I was wondering if it was some replaceable part as it has the nut on top for easy removal

 

It is a Hydraulic accumulator and is charged by a pump/motor assembly I.A.W. the field service manual. As maineah stated it will keep the brake boost after the loss of the main hydraulics pump. I think the manual says for about 20 strokes of the brake pedal. Actually what it says is 20 strokes will bleed the booster accumulator down.

I would say if the pedal is firm and working as it should, leave it alone.

 

Cool... I'll leave it alone.

Thanks
