About this repair
Specialist AR Hydraulic Repair

This listing covers the repair of the AR hydraulic ABS pump fitted to the Vauxhall Corsa D. The fault causes restricted or missing brake-fluid delivery to one or more calipers, which can result in very low braking effort at a wheel and an MOT brake-efficiency failure.

The vehicle may pull strongly to one side under braking, or one wheel may produce little or no braking force even though the caliper, hose and other external braking components appear serviceable. We repair the internal hydraulic fault in your original unit and bench test the pump before return.

Before booking
Common Symptoms Associated with This Fault
Little or no braking effort recorded at one wheel during an MOT brake test
Reduced braking effort at one caliper, commonly the near-side front but other wheels may be affected
The vehicle pulls to one side when braking
Brake fluid does not reach one or more calipers correctly
A caliper appears inactive even after external braking components have been checked
Uneven braking performance without an obvious external cause
No relevant ABS fault code may be stored despite the hydraulic problem
Important: These symptoms can also be caused by seized calipers, collapsed brake hoses, blocked pipework, air in the system or other external braking faults. Those components should be checked before the ABS pump is sent.

Is This Repair Right for Your Vehicle?

This service is intended for faults inside the AR hydraulic section of the original Corsa D ABS pump. It is most appropriate where:

  • An MOT brake test shows very low or zero effort at one wheel
  • The affected caliper, hose, brake line and mechanical components have been checked
  • Brake fluid delivery from the ABS pump to one or more calipers is restricted or absent

AR units only: confirm that your pump is the AR variant before ordering. Send us a clear photo of the complete unit and its label through eBay messages when uncertain.

Simple process. Fast turnaround. Fully tracked.

Pack and send your unit
Remove any external mounting brackets that are not part of the pump, protect the ports and electrical connector, then package the complete AR ABS unit securely using suitable protective material and the prepaid Royal Mail label. Please do not dismantle or separate the hydraulic block from the ECU.
3
We repair and bench test it
Once received, the unit is inspected, the internal AR hydraulic fault is repaired and the pump is tested using dedicated bench equipment. Repair, testing and dispatch are completed within 48 hours of receipt at our workshop, excluding weekends and bank holidays — normally sooner.
4
We return it fast
Your original ABS pump is carefully packed and returned by Royal Mail Tracked 24. Because your own complete unit is repaired, the existing ECU and coding remain with the vehicle, so programming is not normally required after refitting.
Please use the label we provide so your parcel remains fully tracked and qualifies for free postage.

Frequently Asked Questions
What fault does this repair cover?
This service repairs an internal AR hydraulic fault that restricts or prevents brake-fluid delivery to one or more calipers, causing low or zero braking effort and possible MOT failure.
Does an MOT failure confirm that the ABS pump is faulty?
Not by itself. Seized calipers, collapsed hoses, blocked pipework, air in the system and other external faults can cause similar results. Those components should be checked first.
Will the unit need coding after refitting?
Coding is not normally required because your original complete ABS unit is repaired and returned with its existing ECU and coding retained.
What must be done after refitting?
The braking system must be refitted and bled correctly in accordance with the vehicle manufacturer's procedure. The vehicle should not be driven until correct braking operation has been confirmed.
How long does the repair take?
The 48-hour workshop turnaround begins when the complete unit is received at our workshop and excludes weekends and bank holidays. Most repairs are completed sooner.
What happens if the unit cannot be repaired?
We will contact you and arrange a full refund under our No Repair, No Fee commitment.
