& lcv braking

Juratek  have been supplying the automotive industry for over 20 years with the highest quality brake discs and pads.

The design and production of our brake discs and drums is controlled by our own engineers and every batch received is fully checked on our precision measuring machine.

All pads and shoes are approved to ECE R90 regulations. But we take our quality testing much further, by using the OE industry designed tests SAE2521 & SAE2522

 

Juratek employs a team of professional engineers who have developed the products to today’s industry leading standards.​ Using the latest Computer aided design software 3D  models are produced based on measurements taken from our coordinate measuring machine (CMM).  These models are then converted into 2D manufacturing drawings. These models are also used in the routine inspection of the products once manufactured, to ensure conformity to the original design.

Initial Performance Strip

The Initial Performance Strip is added to all front application brake pads. This strip improves the performance of the brakes during the initial running-in period

As you can see the addition of the Green Stripe to the pad surface gives more friction, hence better braking, from the very first stop, in comparison with the same grade of pad material without the Green Stripe.
 

SAE2521 (AK Noise)

The effectiveness of our premium anti–noise brake shims is assured by tests we carry out to SAE2521 – the test developed by the OEM automotive industry to measure the noise performance of a vehicle braking system.

The test is carried out on a test rig comprising a full  vehicle corner and is contained in an anechoic (sound-proof) chamber to prevent external noise pollution.

All Juratek brake pads are ECE R90 approved for fitting in any European country. The aim of ECE R90 is to establish a common minimum standard of braking performance, product integrity and manufactured quality for replacement brake linings across the whole of Europe. Previously, the market was unregulated and products of dubious performance and quality could be sold with impunity with consequent safety risks to all road users.

 

SAE2522 (AK Master)

This test programme used by the OEM brake industry to measure and develop brake pads for OE use and assesses their performance at the more extreme values of braking performance not covered by the ECE R90 test regime.

With fixed calipers, the entire caliper is solidly mounted to the axle or frame and there is a piston or pistons on both sides of the caliper. The pistons push the two brake pads onto both sides of the disc and therefore not require sliding pins to function.

The fixed caliper can apply more power and apply that power 
more evenly during braking. They also provide a better feel through the brake pedal whenever the driver applies the brake which is preferable for luxury and performance vehicles.

The complete caliper assembly comprises two structural  parts – a caliper bracket which is solidly mounted to the axle of the vehicle and the caliper body which houses the hydraulic pistons.

The inboard element of the caliper body contains the pistons and the hydraulic pressure created from the brake pedal via the master cylinder  initiates  the direct

clamp of the piston side  brake  pad and  the resulting

reaction  force  on the  outboard side  of the caliper  clamps the  outboard  side brake  pad  to  the  disc. The caliper can slide either on pins contained within bushes or on the caliper bracket itself.

All Juratek brake calipers are approved for fitting in any European country under BER Regulation (EC) 461/2010. These calipers are 100% new calipers, so no old core or surchages need to apply.

100% Quality Testing

One of the most important tests is the high and low pressure test.

Each caliper will firstly be low pressure tested with a 0.6MPA pressure which lasts for 5 seconds, then a high  pressure  test is done under 4MPA which also lasts 5 seconds. If there is no pressure loss, then the product is approved for sale.

Brake calipers convert the braking effort applied by the driver to the brake pedal into a clamping force between the brake pads and brake disc at the road wheel.

There are two basic types of brake caliper in use:

Sliding Calipers

(also known as Floating or Fist Type calipers)

The complete caliper assembly comprises two structural     parts  – a caliper bracket which is solidly mounted to the axle       of the vehicle and the caliper body which houses the       

    hydraulic pistons.

The inboard element of the caliper body contains the pistons and the hydraulic pressure created from the brake pedal via the master cylinder  initiates  the direct  
clamp of the piston side  brake  pad and  the resulting  reaction  force   on  the 

             outboard side  of the caliper clamps the  outboard  side

             brake  pad  to  the  disc. The caliper can slide either on 

           pins contained within bushes or on the caliper bracket 

           itself.

Handbrake Calipers

Some floating calipers can also be used to operate the parking brake.

These can be either mechanically or electronically operated.

Mechanically Operated

This type of caliper is used for normal pedal braking and the piston is operated hydraulically. However it is also used to operate the parking brake.

If the floating caliper incorporates a parking brake, then it will have a brake lever which is connected to the parking brake by a brake cable.

When the parking brake lever is pulled force is applied mechanically instead of hydraulically.

Electrically Operated

This type of caliper is also used for normal pedal braking and the piston is operated hydraulically. However it is also used to operate the parking brake.

If the floating caliper incorporates an electronic  parking brake, then it will have an EPB (Electronic Parking Brake) actuator fitted. The EPB (Electronic Parking Brake) unit contains an electric drive motor which via a spindle provides the actuation force  to clamp the brake pads to the disc when the holding mechanism is activated by the driver via a switch or button.

The EPB is used as a part of a larger electronic brake control system which can provide safety functions such as automatic EPB engagement to prevent “roll away” in the event of an engine stall and “hill hold” to prevent the car rolling backwards.
