I just want to confirm, see picture there is a wetness on the floor and brake fluid at the bottom of the brake booster. It is a very small leak i checked my fluid reservoir and it is full. So the leak must be very little. Have anyone had this experience? Anyone knows a place to get a brake master cylinder asap? Thx

Yep this is the brake master cylinder leaking. I don't know where you can get them in the US but in the UK there on eBay. So might be worth a shot

Can you pls send me the eBay link. Thank you
 
Well, since you have the truck based JB I think the part you need is MB407062 (15/16"), but I don't think it is different from the L300 van's MB407060, nor the US market Van/Wagon MB407061... The latter part is readily available at the moment; I bought one on closeout because it was just too cheap to pass up.

I think i am able to source one. Will let you know thx
 
@sk66 I install and bleed the brake master cylinder when i got ready to bleed the rotors i discovered there is no bleed valve on the left rear wheel. How do I bleed the left rear wheel? Also my brakes feel good without bleeding them, should i still bleed them or should i just let them be.thx
 
Follow the workshop manual for the brake bleeding procedure. There is no bleed valve on the left rear, since they're in series bleeding the right rear will also bleed the left.
 
Can some pls send the master cylinder part # from Oreilly, seem that my master cylinder is leaking again. Autozone has it but won’t get here till Tuesday. I am trying to leave for trip monday. I had the Oreilly part # last week but I cannot locate it. Thx
 
I just recently installed the part from Autozone. It fits the L300 just fine.. All you have to do is loosen the top inlet "cups" and rotate them to the right for RHD vehicles. Only had to pull out the dash cluster. Was able to get it all from there. No need to remove the dash.

Thx I got one from Delica USA. Working great so far.
 
Shoot mine isnt prebled and I already installed the master, do I need to remove it to bench bleed or can I do it where it sits?
