Hey guys, I've got a younger brother with a celica (I know its not a 7 but it bleeds the same). Anyway, the rubber around the piston on a caliper ruined and his fluid leaked out causing him to have to use his E brake to stop.

He just put a new caliper, pads, ect on his car but since all his fluid leaked out will he have to bench bleed the MC??? What about if he makes the diy brake bleeder as seen here....

If he uses a brake bleeder like that will he still need to pull the mc to bleed it???

Thanks for the help, brakes isnt my strong point lol

He will not have to bench bleed the master unless the master itself ran dry. Was the reservoir COMPLETELY empty? As long as the master never saw air then a "normal" brake bleeding will take care of everything.

 

I think its completely empty. When the rubber on the caliper went bad it lost all the fluid. Even the line that attaches to the caliper had no fluid at all when he loosened it to replace the caliper. And the reservoir was also completely dry.

I think everything from that caliper to the reservoir went dry

Must have been a huge friggen leak; probably going to have to bench bleed then. Normally you can find a universal type kit at the auto parts store that has some little plastic hose adaptors and some rubber tubing. Basically you disconnect the hardlines from the master and pop in the little adaptors that let you run a short rubber hose from each circuit into the brake fluid reservoir. Add fluid and pump the pedal until you see no air bubbles coming out the hoses (should only take a few pumps). Then reattach the hard lines and bleed the system normally. Be certain you have plenty of brake fluid on hand, you'll use quite a bit if the system is empty.

You don't have to actually remove the cylinder from the car to do this.

 

Yea, it was a huge freak'n leak, actually his pad fell out, and the piston rubbed on the rotor till it was gone and all his fluid came out.....I think he was overdue for some pads what do you think? lol, at least it'll teach him how important maintance is.

Awsome....I'll tell him to get the kit then!!!

So the diy garder pump bleeder thing wont take the place of bleeding the mc seperate then right.

Thanks

Correct. If the master itself has air in it the only way to remove it is to bench bleed. After that though you can certainly use the diy pump to bleed the rest of the system.

 

Thanks for the help man
