1. Ensure slave cylinders can slide (check if back plates have been powder coated that the coating does not go soft with heat and jam slave cylinder) If cylinders do not slide remove them clean back plate and cylinder and lubricate with Coppaslip.

2. Check there is not a wear groove in the back plate where the handbrake lever pivots as this can cause the slave cylinder to jam on back plate.

3. Ensure raised pads on back plate that the edges of the shoes rest on are perfectly flat. Any lips or steps will cause shoe to stick and rub on drum building up heat and glazing shoes. Or they will give a false shoes position when adjusting. Apply a minimal amount of Coppaslip to the pads so as not to contaminate shoe material.

4. Clean drum with brake cleaner

5. Adjust shoes as per manufacture instructions

6. Brake from 60 mph to 30 6 to 7 times using a steady brake pedal application. A gentle pull on the handbrake lever to ensure full engagement of the new shoes will help. Do not left foot brake, lock wheels or come to a complete standstill.

7. After the 7th slow down allow brakes to completely cool (do not park up with foot on brake pedal or handbrake applied as this will cook the shoe against the drum)

8. The brake shoes will now work from cold. Remove drums clean out re-adjust.

9. A good practice is to bleed the brakes at this point (not to remove air). This replaces the fluid in the slave cylinders and or callipers. This fluid is the only fluid in the system that is affected by the temperature from the brakes so de-grades.

1. As above but slave cylinders do not slide.

2. Check adjusters are free to turn and the serrations are in a good enough condition to hold their position on the shoe pins (i.e. they do not slip off and release adjustment when pedal pressed).

The material should not be confused with old technology materials and old technology bedding in procedures should not be used.

If you do not bed them in they will glaze.

If you bed them in correctly you will never have to do it again unless you drive incredibly gently on brakes and glaze the shoes. If this occurs rough up shoe material with 60 grit emery and repeat bedding in.

A 1955 Aston Martin DB3S/104 has reduced its test track lap time thanks to some new brake linings from Mintex Classic, which will be officially launched at Goodwood Revival, as well as other work carried out by Blakney Motorsport.

Mintex, which has been manufacturing brakes for more than 100 years and has a long-established reputation for aiding motorsport successes, has launched Mintex Classic to service the classic car market, both racing and road use, for pads and shoes.

As the pioneer of the brake discs and pads that we know today, Mintex has extended its racing range to ensure parts are readily available on a wide range of classic cars including Ford, Jaguar, Aston Martin, Rover and Triumph. In addition, an exclusive bespoke service for more specialised cars will also be available.

The 1955 Aston Martin DB3S/104, which is owned by Steve Boultbee Brooks, was one of the first cars to experience Mintex Classic’s bespoke service. The manufacturer’s team of experts worked closely with Steve and Blakney Motorsport to develop the perfect friction material for his car. In recent times finding a replacement shoe lining has been a struggle and the car had been using an extruded roll “industrial material” which has a relatively high rubber content to make it flexible. This, with the addition of shoe platforms that were too twisted and bent, had seriously impacted on the car’s braking performance, particularly during races where the car reaches up to 140 mph and brake temperatures are 400 Celsius plus.

Mintex replaced the shoes and then completely relined the brakes using an advanced friction material. This not only more than doubled the car’s overall braking performance, but has also had a significant impact on Steve’s racing times, including a podium finish at the 73rd Goodwood Members’ Meeting.

Lawrence Bleasdale, Strategic Sales Director of Mintex, said: “Mintex Classic race material has been specially designed for the classic rally and circuit racing industry as the pads/linings reach a higher temperature than standard cars. The exceptional results that Steve’s Aston Martin DB3S/104 has achieved are testament to the quality of the new Mintex Classic brakes and the unique knowledge from our team of expert technicians. We have also specifically produced a classic road material for the non-racing classic owner, to provide a consistent and quiet road performance.”

“Mintex Classic will be officially launched at this year’s Goodwood Revival with Steve’s Aston Martin DB3S/104 competing in the Freddie March Memorial Trophy and showcasing his new brake linings.”

The brakes will use modern materials on historic back plates and platforms to refashion pads from the late 1950s and shoes from earlier, helping Mintex recreate a period of racing dominance.

Steve Boultbee Brooks said: “As someone who is passionate about cars and racing, I have been absolutely delighted with the performance and results achieved by the new Mintex Classic brakes. While the car still runs perfectly, it was near impossible to find a friction material that performed well under such strenuous operating conditions. Mintex’s expert team has been fantastic from start to finish, advising on the best solution for my car. I can’t recommend them enough – the results we have achieved so far certainly speak for themselves!”

They work really well. Tried and tested on my rally car and i need brakes from cold for the auto test type targa events i do and to be able to hang on at high temp when doing night rallies using the Lake district passes (my rally car is on drums all round) Whilst some people may think they are over the top for a road car and or expensive you want to check what other people are charging for a similar size brake shoes. I have a good deal on them.
