Sealey VS820 Brake and Clutch Bleeding System

Excellent piece of kit, well made, Reasonably Priced, works very well and easy to use, All 4 corners of brake system bled in 45mins to remove air and renew all fluid, brake pedal now right at top of its stroke and firm in operation. Customer Service/Technical Department Very Helpful in providing me with a different master cylinder cap to pressurise system as my Subaru Forester has a different fitting cap to the 1 supplied, supplied one is screw typeand mine is quarter rurn 3 lug fitting, ordered12pm, arrived next day, EXCELLENT SERVICE, ALL ROUND, WOULD DEF. RECOMEND, TOOL SO EASY TO USE, BUT;- "MAKE SURE PRESSURE CAP FITTING IS CLIPPED DOWN SECURELY OR IT WILL POP OFF WHEN CLIPPED ON" (MY FAULT NOT TOOLS!! "FEEL IT CLICK" BRILL TOOL,well worth money.

I wish I had bought this year's ago. Really easy to use, no leaks, and really easy to position because the brake reservoir cap has a connector on it that rotates. Much better than anything I have used before. It's good quality

A brilliant product for pressure bleeding the brake system without spending hundreds on electronic versions. Way better than the type of bleeder that uses pressure from your vehicle's tyres! Definitely recommend. Great value on Amazon too compared to other sellers and platforms. Used it to get the brakes working again on an Vauxhal Movano (Renault Master). If you know, you know.

There was diverging reviews on this tool. On one end, some people say it's wonderful and is just the tool to flush a braking system, especially if you have ABS. However, on the other hand, people said it leaked etc. It's not a 'cheap' throw away tool, but it's more convenient than the other kind which requires a spare tyre at the 'right' pressure to do the job, so I decided to risk it. First, I received it and tried to pressure it up "empty" and, as quite a few other people have discovered, it was pointless, completely rubbish, wouldnt keep the pressure at all. So I tried to locate the problem, removed the plugs and stoppers, cleaned them, removed any plastic molding bards, and tightened it up properly, and it DID keep the pressure up against my hand after that... So once the time arrived to use it, as the instruction requires, I added brake fluid etc, made sure the pipe was filled reasonably well... I used another suggestion from another reviewer and used plumper's tape on the braking fluid cylinder thread, before screwing in the adapter. THEN I applied a bit more pressure, and lo'and'behold, the hole thing was airtight, and I managed to get about 10psi easily without even trying, and no leaks. I then went on and bled the four corners, twice, and I think I used perhaps 1/2 pint of fluid in total to get the 4 corners running nice and clear. Conclusion, GREAT tool, but require a bit of preparation. A bit expensive, but given the horror stories I've read about people bleeding brakes for ABS equipped cars, I'm certainly not complaining! EDIT: Used it about 3 times over the last 5 years or so, still works perfectly fine. I don't need the plumber tape on the adaptor, works very well without it. I give it a bit more than 10psi too, and it makes flushing the fluid easy as pie.

I've tried countless brake bleeders and all of them did not impress me .......they either leaked under pressure or just wasn't up to the job..This fluid bleeder beats all of them...even the top named brands. This one is very robustly made and it worked brilliantly. Absolutely Brilliant. Andy Hornby

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.

Excellent product (mine came with a free universal adapter too). Usage is pretty self explanatory but I would say the instructions could be worded a little clearer in a couple of places. I will also just mention three important points: First, I found that on the cap that connects to the vehicles brake fluid reservoir the tube part that goes into the reservoir needed trimming so that the tube stops at about the fluid max mark in the reservoir - otherwise, however I tried to depressurise, I ended up with fluid being drawn back into the bleeder bottle and then having to be put back into the reservoir again. Second, as I think has been said already, you can save on mess / clean up by just filling the brake fluid reservoir right up to the brim and not filling the bleeder bottle - do check the fluid level during bleeding as you won't be able to bleed all the system with one fill on most vehicles and also on the cap that connects to the vehicles brake fluid reservoir the tube part that goes into the reservoir needs removing completely to stop fluid being draw into the bleeder bottle (which defeats the point of doing it this way). Third, the instructions say to just drain the brake fluid out of the bleeder after use, this would be acceptable if you will be using it frequently however as I only use it occasionally I rinse it out using cold water after use and then thoroughly dry it, as the one time I left it with a very small amount of residue in the tubing I noticed upon going to use it again that the brake fluid had started to penetrate through the tubing and was making a mess. Overall I would recommend this over cheaper or for that matter more expensive setups.

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.

This system is excellent. The plunger is metal and should last longer than the plastic one on my last kit. There was an attachment to assist slippery hands tighten down the cap to make sure a vacuum is held tight, and the hoses and quick disconnects were of high quality. I would recommend 100%

Very handy to do the job alone. I recommend filling the car break fluid canister full, then place in this tool around 0,5l more than the total liquid you need to replace. Then close the thank of the tool and pump till fluid goes through the tube and comes out, so that you minimize risk of pushing air in the system. Then tighten the tool to the car fluid canister and start pumping as you find in the instructions. Remember to periodically check the pressure and than you do not run out of liquid in the tool tank. When you are done, make sure to wash with water everything. I recommend it.

Perfect tool

Very good quality and looks like it will last. Didn't realise it Didn't come with a bleed bottle to catch the bleed fluid so I had to order seperately but otherwise happy with the purchase. Also ordered seperate adapters as it only comes with a single 45mm cap.

Lo compré hace más de un año y lo he usado a conciencia purgando los frenos de varios coches. Funciona como el primer dia y la calidad de construccion es muy buena. No defrauda. El tapon adaptador es para vehiculos del standard europeo. He probado en modelos de Ford,Citroën,Seat,Wolkswagen y Peugeot y va perfecto
