I’ve been using ProSlip slider pin grease for a couple of years already. As retired fleet manager who still carries out a lot of servicing jobs for others I was always spending a lot of time removing stuck and corroded pins.
As well as being time consuming (and pricey if someone else is doing it), stuck pins lead to uneven pad wear and poor braking. Expensive and inconvenient at best – dangerous at worst. I had used all sorts of lubricants to solve the problem. The stuff you get with replacement pins is good – but avoiding buying new pins before a normal wear change is better. The heat and forces at work will degrade the lubricant and I always re grease the pins when changing pads. I understand some pad systems are designed to make pad changes fast, and total pin removal isn’t required, but you would not expect other vehicle lubricants to last forever. Pin grease doesn’t either.
A rear pad change (Akebono) from two days ago shows the difference. The ‘4pin’ photo shows (l-R);
1. Pin taken from caliper on previous pad change- it is slightly bent from sticking and took some time to get out. New flats had to be ground on the nut head. Rusty (? lube present). 20+k.
2. Similar to above but with original lube – no bend but replaced at 22k. Once the plating goes and pitting is evident they are very prone to rusting fast.
3. Pin with Pro slip at approx 18k miles. Plating still present and little sign of wear. Came out cleanly with minimal effort – which many will like as working in the wheel arch is tight and often painful.
4. New pin from front caliper just for condition comparison.
The ‘6 pin’ photo shows as above with the (4 from left) lower pin -also 18k- removed still with grommet in place looking not dissimilar to the day it went in! (Vehicle is a 4×4 – cross country and towing are quite demanding on its brakes.)
Living here in the NE of Scotland cars are subject to quite poor driving conditions – lots of rust from dirt, salt and snow. Although this isn’t as cheap as other products people may consider (copper slip, graphite/ valve grease, moly grease etc – just don’t! ) – it does work very well. It’s very reassuring to know Proslip is doing its job especially on something as vital as a braking system. I do not miss the time spent trying to remove corroded pins- especially at night, in the winter or on my weekends.
For a home mechanic, classic car enthusiast or commercial fleet manager this is a worthwhile investment resulting in less down time – and more free time.
I have used the other two products on the recent pad change and refitting the shims was easier and should be slick on the next pad change. It is an area that requires a good clean before pad replacement so anything that eases that task is welcome. Time will tell.
The pad lube goes on nicely and again works well. There are no squeaks or unwanted noises coming from the brakes.
The tubes contain a good amount of product. It does not require slathering on, my last lot did about fifty pairs of pins in a range of sizes (to give an average). The colour coding helps to find the tubes in my cluttered workshop.
I got this product from the manufacturer as I have bought it previously, but it is an excellent product and hopefully more people will use it now it is on Amazon.
Highly recommended for peace of mind and money saved
