SealeyVs820 Brake And Clutch Bleeding System

Very sturdy item made of chunky plastic. Sealy tools are a brand you can trust. It was my first time bleeding car brakes on my own. This pump made the job so easy. I used a blanket to protect the engine bay, just in case of leaks, but there were none. I replaced a caliper and double bled all 4 brakes. Simply attach to reservoir, add 1Ltr or fluid, pump up and then bleed each caliper in the correct sequence. No spills or leaks. Local garages charge £50-60 for a brake bleed, so this item will pay for itself, and I know know the job has been done properly.

After trying to bleed the clutch on my VW Golf mk4 with zero success I decided to try this. Brilliant. Super easy to use. Clear instructions. Made well and I had no issues with the seals as others have had. Recommended if you need to bleed your brakes or clutch.

Positives : this is so easy to use it made bleeding brakes by my self so quick and easy I will be continuing to use this and I recommend anyone to buy this helps detects leaks aswell as being able to bleed systems and has large capacity good quality for the price I would rebuy this is mine ever broke

It initially appeared to be of good build quality but I had trouble getting the filler cap to seal- it had to be done up really really tightCouldn't find anything that was causing it.This is something I would expect in the cheaper imitations available so Sealey dropped a star there.My car needed quite a bit of pressure on the dial to get the fluid running but it succeeded in removing some troublesome air bubbles from the new calipers that a Visibleed kit could not.Overall it made the job easy as you can concentrate on each caliper and not have to stop all the time and run around to the reservoir to make sure to not run out of fluid.

I bought this to flush the brake fluid on my car, I followed the instructions, filled and pressurised it. Then bled each brake, kept an eye on the pressure, occasionally pumped it up. So easy that I bled it a second time for good measure. Completed, cleaned seals etc and put away for next time, really good 👍. There are cheaper ones, but I wondered if the quick release connector on those may not have a quality finish. Having used the old spare tyre pressure type, this thing is a doddle. Thank you.

Sealey not sealy.I could make this product work by adapting the seals but why should I? Its principle is great and I'm sure it would be lovely to use bugt it's another poor quality item from Sealey.If you get one which seals properly this may help you....Remember this will displace alot of air through your brake or clutch system before it pushes fluid through. If you are not replacing the entire fluid and just want to get a better pedal feel you will need to prime the line of the filler cap to reservoir before bleeding. This is still going to put a huge amount of air into a brake or clutch line so plan what you use this for. With DOT4/5 fluid at about £30/L in 2025 you will need a minimum of 1.25L to 1.5L of fluid to use this product. Considering most brake and clutch lines only hold 150ml per cylinder plus piston & reservoir volume this is a very expensive way to bleed brakes.My opinion is its only good for full fluid changes and it would be nice if a bleed tube for old fluid was included but its not.Again would be a doddle to use if it worked.The faulty seal looks to be a standard product fault across a number of recent reviews. The filling cap does not seal. Anyone with any design experience of pressure or hydraulic systems should know a flat seal mating to a flat plastic thread face is never going to work well (hence Sealey realise this and include a spanner to torque the living hell out the cap). Great on a benchtop but not over an engine bay with no room to move. Garden weed sprayers have been doing this better since the 1970s with a simple O-ring. I've just designed my next.......I'm sure this would be a great product but for this price on Amazon, and the amount of poor quality kit being churned out by Sealey recently be very careful before you have a load of airaited fluid. For me zero stars and one less Sealey customer.

Bought this to bleed the brakes after a whole new rear brake setup on a Mercedes Sprinter, I've done brake jobs before and used the two person method. But thought I'd try this out and see how it went. For me the product was excellent, no leaks or having to add silicone grease to gaskets or tightening anything up as some reviews I read stated, it was basically out of the box working. I did pressure test the unit before filling it with brake fluid, and it held a constant pressure over a 10 minute period ( If you wish to do this don't attach the reservoir cap to the line, pump to 15 or so PSI and leave for 15 mins then check guage hasn't moved) which was a good start, I checked for other leaks with a spray bottle filled with water and washing up liquid and sprayed round the caps and found nothing. The build quality is excellent, If you follow a 2 year flush per service recommendation you'll be saving money around your second use, we are a two car household so it's already saved a couple of quid getting it done from the garage. The process is very straightforward, I filled with 1.5 litres of fluid. Used a turkey baster to remove 2/3 of the old fluid from the reservoir on the van. Opened bleed nipples on calipers and waited till no air bubbles present, tighten and job done, overall a very simple process, that's made doing fluid flushes easier with no need to get a second person to help you.
