D3 brakes, replace, upgrade, fix?

**swiftnets** · 24th October 2022, 01:48 PM

Hi everyone,

After having the issue "fixed" 4 years ago by Triumph Rover Spares replacing the booster, our brakes are loosing boost again and a check on the quick connect link in front of the booster confirmed there was oil present.

I guess the issue has re-occurred with the vacuum pump allowing oil through to the booster again. Now, Triumph Rover have decided to cease their workshop and servicing offerings, so I will be doing stuff myself.

I know I could just replace the booster and lines again, but without preventing the oil migrating through it will happen again.

I watched Shane's shed replace his booster and he mentioned both a catch can or an electric vacuum pump from a VE Commodorre.

I have also seen suggestions in other threads about RRS boosters providing a better brake than just replacing it.

Has anyone else replaced their vacuum with electric or setup a catch can?

All the catch cans I have seen are obviously for crankcase, would they still work?

Would either of those options be easier to implement than the other?

I enjoy working on the car, but I don't really want to keep making work for myself.

Thanks all
Michael

I didnt mention it in my reply on my video, but you'll want a catch can that is fully sealed and will be suitable for a vacuum obviously. There's quite a few on the market that have breathers in them which would be no good for this application

That's what I have been noticing.

Thanks to your video, I have no issue doing the actual swap over, I just want to avoid having to do it again, and again, and again....

I am looking at maybe one of these - Proflow Universal Compact Electric Brake Vacuum System, 12v Complete Street Pump kit

Hi,
I did all three in 2018.
Replaced with a RRS vac chamber, added a ebay catch can, and fitted a new ball/spring one way valve mod.
I used the old ball/spring mod to harvest bits of pipe to route to the catch can which is behind the second battery.

No probs since.

Was the RRS booster - SJJ500080?

Is there any specs around as to the required vacuum would be? Shane's test showed 28, the electric pump indicates 22.

Here's my original thread.
Oil In Booster - DIY advice
Unsure of vacuum requirements, but the brakes now work vverrryyy well.
