Brake line caps and plugs (3 Viewers)

[Malleus]

Does anyone have a commercial recommendation(s)? Joey had a little double ended (male/female) deal, out of aluminum, that would have been great, but that ship sailed long ago.

I can find plugs (BelMetric has the deal on M10x1.0 plugs, specifically the Toyota style, at $2.20 each) but I'm coming up empty on caps. It would really be nice to be able to cap off the master cylinder lines and plug the master cylinder ports, for, oh, say a brake booster replacement that you didn't feel like draining the master cylinder for...just spitballing here.

Toyota rubber caps (plugs) (31478-30010) are great for sealing dirt/dust out, but I don't know how long they'd hold fluid; I've never tried them for that.

About 100 years ago, I had replaced some old hard brake lines from my 91. I cut the lines, folded and crimped them closed just after the fittings. I think I have 2 males and 2 females sitting in a parts box somewhere. I'll probably never be able to find them if I need them...

One suggestion

Straight union then a plug

I welded up my own out of spare parts; they are in the top tray of my tool box.

Amazon. I just ordered them last week. Think it was a 10 pack of unions and a 10 pack of plugs for just shy of $20

I just replaced my master cylinder, one hard line, and the three soft hoses from the chassis to the axles.

From reading other experiences, people often end up with hard-to-bleed air percolating in the brakes and ABS and struggle to get it out. I wanted to avoid this and ordered plugs and caps to avoid air entering the system in the first place.

I immediately capped and plugged everything on removal, did a thorough on-vehicle bench bleed of the new MC, pre-filled the new hoses and line, connected the low ends first, and used a pressure bleeder to keep a soft +5 psi as I made the top end connections, letting them spit a bit before sealing them tight.

This worked well and I had a perfectly hard pedal from the first try. I then bled 0 to 3 tiny bubbles from each of the wheels.

Sometimes it's good to be afraid, and being tidy made it a very easy job.

The plugs are available all over the place, but the caps were harder to find. I had to order these from the UK:
