Broken Bleeder Valve with Drill Bit stuck in flush

[THafeez]

Hi guys I was doing a routine brake bleed and all of the bleeder valves were good except one. Nipple broke, then my drill bit broke in there as well. It's a black ryobi bit used to cut wood. I can't get it out because the bit broke off flush with the caliper. Should I get a harder bit and drill through the broken bit then use an extractor? Any other way? I know I can replace the caliper, but that's the last measure so if you have any advice on how to get bleeder screw out with a drill bit stuck in it please let me know. I'm new to working on cars and I would appreciate any advice y'all have.

They make Tools just for removing stuck bleeder screws, but in a pinch, your best bet is to either leave it alone (assuming you have not allowed any fluid to drain) or purchase a reman caliper.

Few questions, after nipple broke:

1- Is it leaking any brake fluid?

2- Does your brake pedal feel spongy?

3- You can use ez out too, if you have them?

Also, if you are trying to drill it out, use smallest bit available, use it very slowly and don't put too much pressure. Create a pilot hole, go one size bigger and eventually brake it. While doing all of this, if it's possible use little bit of 'used' motor oil to keep the bit cool and friction low.

Whatever you do, you're on your own. Its illegal for a shop to machine / drill / tap a brake component.

Seriously?. It isn't in the UK. What about other Canadian provinces, or states in the USA?.

Thanks for the videos and advice everyone.
1. Not leaking. It stayed in the closed position throughout
2. Bled all of the other valves and brakes are tight.
3. Don't have ez out. Will these Screw extractors from home depot work? Screw extractor set
And your method is very good. I'll follow it. Thank you.

I'd look into replacing both calipers and rotors with bigger ones from a V6
Toyota if you plan to keep the car. Cheapest "big brake" kit around, but you may need 16 inch wheels. Hylander also brakes fit. Plenty of info on Toyota nation.com.

thank you sir

Dont touch or do any other types of fixes. People aways get carried away when they break a bleeder screw. You can still easily bleed a system without one. You see the line going to the brake caliper? There is your secondary bleeder. Remove the caliper from the backet and put a block of wood inbetween to hold the pistons in place. Make sure the line is facing up and bleed as normal. Just make sure you crack the line first before you remove anything.

You guys drilling/tapping...or whatever are making more trouble and work for yourselves.

Okay this seems a lot less riskier. Thank you.

You know, I've actually done this at least once that I remember due to a broken bleeder.
It did work just fine.
OTOH, replacement calipers are cheap these days and you can always get one for little more than labor from a yard.
If you rob one off a donor car in a yard, you'll of course check that the bleeder loosens first.
